To have lost one's mind.. Not right in the head. Mentally unstable

Used to describe (generally female) imagery that's suggestive, but in a PG-13 sense rather than an R or above sense.

To be so fucked up that you have no concept of reality.

You've overdosed and your lips go pale (white). You can't really move and everything is tingly so you just need to sit down, you're basically fucked.

to be scared or fear something.

*Bizarre or Strange

a psycho, someone who see's bugs that aren't really there, the amount the person looks around at nothing psychotically determines how bugged out he is. Someone who is really bugged out see's bugs appear then dissapear all over his field of vision only experiencing fleeting moments of relief then panic as he turns his head to realize they are reappear somewhere else. Being bugged out also traces back to christian/devil worship, people who are plagued by more demons witness more bugs.
