designated sucker

the friend in your group, (who's naturally a hoe), sucks all the crusty dicks you don't want to.

Amber: Ew Sarah, that ratchet old man just asked me to give him a blowjob!

*Amber and Sarah look back at their friend Paisley *

Sarah: You know what to do, designated sucker. Drop to those ashy knees and start sucking.
