Sleeptasticles 

A curious blend of the words 'sleep', 'testicles', and 'fantastic'. This word is generally used having made yourself look like a total tit on an online forum by getting drunk and posting random, misspelt messages which provide great and varied entertainment to those privileged enough to be witness to such events, and said drunk poster is going to sleep, or pass out in a corner, or whatever.

The word was coined by Ultimate Metal forum member King Richard in a highly entertaining post named 'paaartty!1!'

King Richard: jagerboms are the shit!!!!!!! fuckin wasted mangs! FUCkyESS

Krigloch the Furious: gross! Redbull is terrible.
Irish Car Bombs are the way to go

King Richard: kriggles is the man too1!
