red pants 

A mature woman who is on her period but still chooses to dress up and go out.

Also a foreign dude who plays electric keyboard and sings old songs in a restaurant/bar.

Betty's got her red pants on but that's not stopping her from making out with that Jagger dude.

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.
