A bastardization of the word mustard, for people who like to garnish their burgers and
dogs and
swear at the same
time. Goes well with katshit.
Joe: All this burger needs is a
little mouseturd ... mebbe some katshit too.
Celia: <sigh> Can't you say anything without
fucking swearing for once?!
Joe: <rolls his
eyes> Tse, I'm just kidding, for fuck's sake!
