The act of making out with a parter, but in such an obnoxious and unskilled manner that it sounds like the partners are pounding two fish together.

When a woman wafts her putrid vaginal fumes around a room full of people. If your cat comes to you expecting tuna you know you're ready.
"We were at the movies and some girl started slapping tuna. That pussy stank was so strong that upon leaving I noticed a few stray cats had come in."
