The way most Canadians pronounce the slang insult, "Twat".

TWOT - Total waste of time

It can be a useless person or a useless object or action.

Variant of twat, someone who is twattish but not quite that bad. Also used in a similar manner to feck, that is a polite replacement that can be used in mixed company.

Someone, who without effort, makes a right proper useless waste of space of himself. Not annoying, just a useless twot.

It's an acronym for 'total waste of time', often used on the internet, to describe things (pictures, videos, etc.) that someone wished they hadn't watched.
