UK slang: a very overweight man, in very brief swimming trunks, hanging out at your
holiday hotel
pool. His trunks appear to have a
budgie, or other small bird, concealed down the front of them
OMG, check out the
budgie smuggler! What's wrong with
swimming shorts?! Do you think that if he had a mirror on a
stick, the budgie would peck at it? etc...
