Use to describe an event that failed.
Or a event that goes very bad.
Also referred to a crap movie.

Abbreviation from the feature film 'The Human Test' the biggest movie failure since Citizen Kane.
Mostly used in the UK where the movie has been made.
Oh man, that production was THT.

I tried a move on that girl yesterday, was fine at the beginning but turned THT when she saw me naked.

Oh dear that movie was a copy-cat of THT.
