Reports suggested Gemmell had used social media to brand the Light Blues boss as "a p****" after McCoist complained about his side being asked to play four games in 11 days, culminating in the Scottish League One clash against Stenny.
McCoist laughed off the incident, which dominated Sunday newspaper back pages, but he believes the remarks serve as a further reminder to his own players to exercise caution when using social media.
Speaking after Rangers' 2-0 win, he said: "I get called worse in the house to be honest with you.
"I reckon about 60 per cent of our dressing room agreed with him - that was the concerning thing!
"It was probably a bit ill-judged but I'm certainly not going to throw the toys out of the pram. In my time at Rangers, I have been called worse.
"He said to me 'You know what I meant, didn't you?' To which I replied 'Not really!'
"But it doesn't matter. We are all big boys and we just get on with it.
"I think he did miss the point - my main gripe was the fans being asked to travel about to three or four games at this time of year.
"He maybe read the situation wrong. I wasn't complaining about the amount of games, I was just trying to fight the fans' corner."
McCoist added: "I'm fed up saying to our lads about Twitter because with the flick of a switch it's global. There are no secrets.
"It's a different era from the one we were brought up in. We could certainly get ourselves in enough trouble without Twitter.
"Twitter just seems another instrument to get them into trouble so I'm not a fan of Twitter.
"We have words with our lads as often as possible, just to tell them to watch what they are saying and watch what they are doing on Twitter."
Meanwhile, McCoist had no complaints about a red card picked up by Arnold Peralta late in the first half, just days after Bilel Mohsni saw red following a flashpoint at the end of Thursday's game at Airdrie.
He said: "My first reaction was that it was a booking but I've got to be honest, I'll look forward to seeing it again and it probably was a red.
"He was very high and I was maybe being more hopeful that anything else by wanting a yellow card.
"The referee was pretty well placed to see it and I don't have any complaints to be honest.
"It did set us back a bit and it changes the whole outlook of the game.
"In terms of the discipline side of the challenge, it's frustrating and disappointing because he gives the referee the opportunity to send him off, which he did do.
"Then they've got an extra man and a lot of good teams will use that extra man."
A goal in each half from Nicky Law secured the points for the league-leaders at Ochilview.
McCoist added: "It wasn't easy on the eye but after going down to 10 men we just wanted to see the game out and get the three points and we did that fine.
"They were great finishes from Nicky. There was lovely movement off big Jon Daly for the first one and the second one looked like a brilliant strike.
"I look forward to seeing that one again."
Asked about the Twitter incident, Stenhousemuir boss Martyn Corrigan said: "That happened last night and is something the club will deal with next week.
"We can only comment on stuff I do and say. Whatever happens off [the pitch], we will deal with internally.
"It certainly didn't distract us or our game-plan. You need to be very careful with social media. I don't think it overshadowed the game."
