One that always annoyed me is when it is around the holidays, when stores advertise gifts for men. They always assume a guy is into toilet humor, beer humor, assuming they’re a lumberjack who needs to survive out in the wilderness, are into bbq-ing all of the time so gotta have those available all year around for some reason.
Even when I used to have identified myself as a guy, I never once fit into any of those traits. Just because guys grow beards, doesn’t always mean they’re chopping wood somewhere and always wearing plaid.
Big penises being more manly or making you a better lover. I’m sure wars have been started by men who were upset with their dick size and would do anything to make up for it.
