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"
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
