it's a common theme in movies, books, etc
'guy doesn't want "manly men" to know he's not one of them so he lies to fit in'
there are people i work with that would give you immortal hell if they knew you had that dragonball z shit video gamey thing in your sig. they hunt, they drink, they smoke, they like football, they have facial hair, they use curse words (but not around women) and they're vulgar.
average person would try to fit in or they'd get picked on non-stop. we had a new guy come to work with gel in his hair one day and they gave him shit over it for 2 years until he quit. to this day, he's that "faggy fucker"
he was straight, he was a decent guy, but he wasn't a "manly man" and he caught shit for it.
you've really never encountered this?
