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...
