When you're doing a girl and her vagina is bleeding.

Caution: Can be more messy than normal sex.

Red Sex

A mispronunciation of a baseball team of Boston Red Sox by some female news announcer on Fuji TV about 15 years ago, which became a hilarious meme for another few years.

This similar incident also happened with Chicago White Sox about the same time, which was mispronounced by a middle aged male news announcer on NHK.

White Sex and Red Sex are different, so choose the colour wisely!

Red Pants of Sex

Similar to the elusive Purple Shirt of Sex, the Red Pants of Sex refer to the glorious pair of y-fronts worn by John Watson. The Red Pants originally were the devices of the brilliant Reapersun on Tumblr. The Red Pants of Sex even have their own day of the week (Monday) and are loved by many. In some parts of America and the UK, they are worshipped by many pubescent teens.

God save the Red Pants of Sex.
