The act of accidnetally bumming one's younger brother while having to share a bed on family holidays.
Younger Brother: What the f***!? You just anally raped me! You sick f***!

Older Brother: I'd say it was more of an anal trespass as I was unconscious and just rolled over funny.

Younger Brother: Oh that's alright then.
