When you go for a turd after someone puts bleach in the toilet and you get a stingy cornhole
"Dude, Aw, Acid Splashback"
"I don't know how to tell you this, but you have a serious case of acid splashback"
when you do acid and crack your neck and get high again,
ted: what the fuck are you doin you almost hit that car
jack: dude i just had an acid splashback
