Isosceles Dongaloid

When you carefully shove Doritos, pizza slices or other triangle-shaped foods very carefully into someone's asshole for sexual pleasure. It is done is such a manner as to not break or mess up the food in any way.

isohel

an isohel is a a very SEXY group in desperate need of therapy. they claim they are okay but all day long they watch vent edits and listen to xxxtentacion like 2018 called they want their songs back! When most of the members are inactive, the other will usually spam and give off schizo vibes- reason number 23984 why they need a ward. They are (sickening and probably a loser in their offline lives) best baes.
Day 69 in isohel ward:

Raech: "arch"
Kuroo: "is having a threesome with kuroken"
Raech: lets listen to 1D songs
Arch: sure! *plays changes by xxxtentacion*
