Mateo: Heh Heh, nope.
Adrian: Get outta here bro, you such a yuckster
Mateo: Now what the actual fuck does that mean, Adrian? Just… st- stop making up words. Like, maybe two or three words is fine, but… 80 or 90, that’s… that’s a lot words man.

I can’t help that I’m a shiitake yuckster. I’ve smelt this way since I was small. It’s not my fault I was born with the uncool virus!
