Used as an insult of a similar nature to numpty. Twateye is not related to Cockeye.
The Twateye had fallen off his bicycle again. Foolish numpty!

An insult for an ugly person whom you don't like, especially if they have beedy, untrustworthy eyes. Helpful if one is staring at you or your girlfriend, you are drunk and want a fight.
"Who the fuck are you looking at, Twat Eyes?"
