Every day, the Daily Dot finds something that people on Facebook are sharing and, in turn, shares it with you—with a little explanation. Here's today's share.

A British man’s comedic rant on a sanitary napkin company’s Facebook page went wildly viral Tuesday, gathering almost 40,000 likes in 20 hours.

Apparently, Richard Neill watched a number of Bodyform Maxi Pads commercials as a boy, noticing they often depicted active women having the time of their lives during their period, and was disappointed when he found out the truth:

As a child I watched your advertisements with interest as to how at this wonderful time of the month that the female gets to enjoy so many things ,I felt a little jealous. I mean bike riding , rollercoasters, dancing, parachuting, why couldn't I get to enjoy this time of joy and 'blue water' and wings !! Dam my penis!! Then I got a girlfriend, was so happy and couldn't wait for this joyous adventurous time of the month to happen .....you lied !! There was no joy , no extreme sports , no blue water spilling over wings and no rocking soundtrack oh no no no. Instead I had to fight against every male urge I had to resist screaming wooaaahhhhh bodddyyyyyyfooorrrmmm bodyformed for youuuuuuu as my lady changed from the loving , gentle, normal skin coloured lady to the little girl from the exorcist with added venom and extra 360 degree head spin. Thanks for setting me up for a fall bodyform

The post’s popularity dwarfs that of Bodyform’s own Facebook page, which has a comparatively paltry 4,000 likes. Since Neill’s post, several other men have copied and pasted the same comment onto the product’s page for some reason.

“No response as yet but I'm waiting on royalties for all this free advertising,” Neill commented in response to his post’s popularity. He might have gathered some free advertising himself, though: he’s been plugging his own novella, Someone To Share My Beans With, in the comments.
