Yeah, I always had PE early in the day. Maybe right before lunch or last period there’d be more goofing off because the lack of time pressure. Seems plausible, anyway.
Main point is this: the few guys I knew who dorked around and razzed each other making faggot jokes once in awhile all grew up straight, got married to actual biological women, and have kids.
My alma mater is all-boys. When guys don’t have to look good for the ladies, less attention is paid to making oneself presentable in street clothes, leaving more time for general rowdiness.
And that’s all I ever saw - general rowdiness, which often got pretty physical, like strong young bulls asserting dominance.
