when i was pretty young i called my sister a whore i had no idea what it meant, heard it in the street..needless to say i got my mouth washed out with bar soap.. an that was awful tasting stuff...i was a bit more careful with what i said after that..
I saw my sister smoking pot and called her a dead head. She laughed and said I should say pothead. Dead heads followed the dead she explained. I was confused at 10.
