Jon: I bet you wish you were a little nicer to me now, huh?! You think I didn't hear you call me "Eduardo Squidwardo" behind my back! I'M GONNA GIVE YOU LOT'S OF DAMAGE!
Any episode of SpongeBob SquarePants in which the character, Squidward Tentacles, is unfairly injured/stripped of any dreams or hopes for that episode for the sole purpose of him being Squidward and being the "bad guy" when in reality, he's the character we sympathize with. Also noted by an abnormally large IQ drop in SpongeBob or Patrick just for those episodes as well.
Fan 1: Did you see that new SpongeBob episode?
Fan 2: Yeah, it was a total Squidward torture porn.
Fan 1: I know, I felt so bad for Squidward!

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
