"So I saw Alex walking to class and he completely blackholed me."
The sick-to-gut feeling you get when your favorite radio station plays soundgarden's blackhole sun song way too much.
OMFG! I am so blackholed! If I hear blackhole sun one more time im gonna puke all over my steering wheel !
To exposed ones anus to an unexpecting victim by the spreading of the ass cheeks.
Dude the other day I was going up the stairs and when I looked up I got totally black holed.
