I am going to a fancy dress party and have to be dressed as something beginning with "N". Can anyone help. Nun , nurse , napolean , norma desmond, norma jean, navy officer , noddy, nelly the elephant , nelly the rapper have already gone!!!!!
Numpty?
I always imagined they looked like a potato but when Googled, urbandictionary.com says:
numpty idiot muppet fool numptyesque prat retard spamhead stupid tool black knees chav **** eejit loser moron numptwell
I wouldn't go that far myself, but go for the geek look maybe?
