Basically another way of saying retarded but when retarded doesnt cut it theres retastic which is worse than retarded. Can be used literally or not.A mix of retarded and the end of fantastic but using it to describe something they are definatly not fantastic at all. Usually used to describe someone who is severly phyiscally handicapped and over-super severly mentally retarded, there face is usually deformed too.
Literal sense: Person 1: Dude did you see that kid that was eating his own snot,drooling with his mouth open and poking his mole at the same time.
Person 2: Yeah that kids retastic
Non-literal sense: Person 1; AHAHAHAHA IM A LEET HACKER YOU SUCK YOUR A PRICK YOU DICK LLEET HACKS FOR THE WIN.
Person 2: Your fucking retastic.
Person 2: Yeah that kids retastic
Non-literal sense: Person 1; AHAHAHAHA IM A LEET HACKER YOU SUCK YOUR A PRICK YOU DICK LLEET HACKS FOR THE WIN.
Person 2: Your fucking retastic.

To suddenly throw up in the middle of drinking festivities and once again taste that delicious bucket of gourmet "moules provencale" you had an hour earlier.
Minutes after downing a creamy and explosive yaeger bomb, it dawned on Bangkok Joe that his body was unhappy. Stumbling out of the raucous Irish Pub he retasted all the earlier mussels he had gleefully consumed hours earlier. His worried friend followed him with a bucket of water and washed away the retasting episode from the sidewalk.
