red bottomosity
having the big red bottom. when a lady baboon is "in the mood" for luuurve she displays her big red bottom to the male baboon. (apparently he wouldn't have a clue otherwise but that is boys for you) if a human being has the red bottom, she is attracting a lot of sexual attention from a lot of guys
"loads of boys were asking me to dance last night, i must have been displaying my red bottomosity"
