look up any word, like bae:
dvt stands for Deep Vein Thromboses, which is a disease, but can be a metaphor for getting the remaining necessary amount of kills in a counter-strike round, and getting the defusal.

A counter-strike term meaning you just killed over 3+ people and rush to get the defuse, if a teamate is already defusing than that player automatically TK's them because he is a greedy bastard.

Synonym: A defuse whore.

Except in this case, the player actually gets kills before he get's greedy for the defuse.
Dude nice three kills! I got the defuse though man don't worr- *TK's player* WHAT THE FUCK MAN, why'd you pull a dvt? fuckin scrub.
