look up any word, like eiffel tower:
 
1.
N. A loose toilet seat likely to slide left or right while seated upon it, sometimes sliding completely off the rim of the bowl. A tilt-a-whirl can be particularly dangerous for men when the seat slides too far and pinches off the sexual organs during defecation.
The men's room here is completely unsafe, a tilt-a-whirl with no ass gaskets.

Hook up with a girl, then using the time it took you to finish as a countdown, find another girl and hook up with her.
It took me 20 minutes to finish with this girl, so I pulled a tilt-a-whirl and in under 20 minutes I hooked up with a different chick!
