Sexual act during which a female sits atop her partner (gender irrelevant, though originally adopted by partners of opposite sexes) who is on all fours, being ridden like a horse. The female stimulates her clitoris by gyrating upon the raised bumps of the spine.
Yeah, she went for a tickleback last night, my back was soaking.

Get the tickleback mug.
A pickleback but with tequila; typically silver (also blanco or plata) tequila.

A pickleback is a shot of Jameson chased by a shot of pickle juice. A tickleback replaces the Jameson with tequila.

This shot is great for people who don't like Jameson shots but are still looking to chase with pickle juice.
Want to get a round of ticklebacks?
