Sustrated 

When you’ve been sussing for a fat minute and you think you might be gay, but you’re frustrated because you would be disowned by your devotely Christian family.

Billy was going through the J.C. Penny catalog when he suddenly popped a boner to one of the guy models. Sustrated, he went and fapped it out to get out all of his anger.

Sistay 

The term used for someone who stans Stray Kids (KPOP band) but is also a follower of any religion. One that follows Stray Kids must not be an angel, because all Stays are crackheads (Not legit, just joking). Therefore they are automatically a sister. Sister + Stay = Sistay.

Omg Sistay can’t wait for Stray Kids new album!

Looking forward to it sistay!
