TST 

Abbreviation of Typical Slut Text.

Typical Slut Texts can crop up at any time, even when you think all is well (not to be confused with Genital Warts)

Girl: "I love spending time with you. xxx"
Guy: "You too, you're great! xxx"

*Next day*

Guy: "Hey, what you up to? Hope all is good! xxx"
Girl: "Hey i'm in town x"

BOOOM TST!!!!

TST 

TST is also known as the pussy version of SWAT, the retards who choose to join TST are known to be proud of being held "Stand-by". TST only allows foreign faggots into their team and a bunch of people with no aim, their ideal applicant would be an EXCELLENT roleplayer who can't aim at all.

SD weebs: Hey Bane, I heard you have no aim, why don't you try out applying for our TST team?

Fireworks: Ahahaha, what a bunch of sad pricks, you're all so sad and have no aim.
