look up any word, like wyd:
 
1.
A slightly creepy hug from behind, usually a surprise and always lasts too long.
Is it weird that my googly-eyed neighbor used to call me his friend and backhug me when I was 13?

2.
Anal sex from a dirty Brazilian man.
She flew all the way to Brazil for his special back hug and all she got was H.I.V.
