Huh?

Walking from class back to the parking garage took such a long time tonight! I got back my resource folder/box and strangely I swear it's heavier now than when I brought it in. Of course tonight my bag was heavier than normal and I choose to wear heels. Smart. During the whole walk, there were these 4 guys just conversing about gum in front of me. Apparently, they were trying to find out what types of gums they all ate. According to them, there are 2 categories of gum, gay or fun gum. In my terms, I would think gay gum meant like fruity gum, not that I categorize my gum like that. So one guy explains that fun gum is stuff like Bubblicious and Big League, while gay gum is like Trident and Dentyne, stuff you use to freshen up your breath. I'm really not seeing how gum you use to freshen your breath is considered gay gum. Is it because it's gay to want fresh breath? Well what if you just enjoyed the minty taste, I mean, people don't eat mint chocolate chip ice cream to freshen their breath. If anyone can figure out their rationale, please let me know cause I really don't get it.
