A plant like, socially uncomfortable creation that drifts across bad jokes and awkward conversations. Usually of the bearded variety, and most of the time appearing to have a cranium with a large circumference to encase all of their shanter (shit banter). Despite these obvious failings, olly trumble weeds are good to have around to make your banter look superior, and you look like a cool dude.
Who's your mate? he's a right olly trumble weed!
