A topical clitoral stimulating gel, designed to help achieve or intensify female orgasm.
I put some O gel on my girlfriend last night after I had her bound to the bed, and it drove her nuts!

Katie: My vibrator just doesn't seem as great as it used to.
Grace: Have you tried using it in the shower?
Haley: Forget the hot shower, Katie, you need to get some o gel!
