A treebo is nastey creature. Usually in the form of a Greebo
, treebos will meet up everyday at a big tree in Milton Keynes City Centre, England. From here they will smoke no less than 20 cigarettes each, scream for no reason, make friends with Chav
s (who will beat them up later), and compare STI's.
In basic terms they are Chav
s with a different dress and speech code.
