I'm going to unicycle to the store for more beer.
Running around in a circle (almost similar to the joy of little girls running around dat maypole) can take place for personal amusement.
The crudely based derivatives include:
Uni- (contraction of 'unicorn' in this case; not meaning 'one' or 'single')
Cycle (as in the specific arrangement of horn-to-ass positions, creating one continuous loop)
2.Boy: "Weirdest circus ever."
Girl: "Oh, I didn't get to see it. What was it like?"
Boy: "There was this -this... unicycle! A bunch of clowns were riding it, too!"
Girl: "That doesn't sound too bad, I mean, ALL of those clowns on one unicycle? What's so weird about that?"
Boy: "Y-you don't wanna know. I... I think I'll g-*hurk* -go and lie down for a little bit..."
Girl: "Huh, that's weird. I usually find unicycles to be arousing... Hehe, hornplay."
