thwunk
Thwacked, unthunk, undone and unfun. That feeling you get right before your face eats asphalt and also that feeling you have right after you stand up... If you stand up.
"That little brat, I thwunked her shit right up." "As puke was rising in my throat on the roller coaster I felt completely thwunk." "It's a bad moon tonight, this drug combo thwunks"
