A thot exterminator is usually a male in a group who go around exterminating thots because thots are useless pieces of no-good trash that go around acting like daddy’s girl . Thot exterminators are usually packed with muscle and kill thots by beating them with fists.
Exterminate is the sound a Dalek makes before it fires its Extermination Ray. So far, only two things have negated its effect: a fully-functional forcefield powered by an extrapolater; the Time And Relative Dimensions In Space, directed through Rose.
Dalek: Exterminate!
Snake: S***.
ZAP!
Dalek: Hasta la vista. BABY! EXTERMINATE!
