“M-E-N-S-T-R-A-T-I-O-N.” No dude, that’s not how you spell menstruation.

In a new video, BuzzFeed asked five guys to explain how periods work and the results are undeniably funny. Armed with a pack of menstrual pads, a box of tampons and a drawing of the female reproductive system, the dudes hilariously try to figure out what’s going on down there.

Some of the men were fairly well-informed about menstruation, while others admitted they had never actually seen the associated paraphernalia. “This would be perfect for my nosebleeds when I was a kid,” one guy said while attempting to explain how to use a tampon.

When asked what they would do if men got periods, one guy replied, “I’d bitch about it… I’d bitch about it all the time.” Another answered, “I’d probably do exactly what women do: I would go through my day pretending like nothing was wrong with me despite the fact that I was in a lot of pain.” Sounds about right to us.
