A shockingly devoted form of Southern hospitality where things get a little… turbulent. It happens when you're on the receiving end of an enthusiastic blowjob, your partner suddenly feels queasy and throws up in their mouth, but instead of bailing out, they power through the storm and finish what they started—swallowing both pride, your ejaculate, and their throw-up like a champ.
"Man, I thought last night was over when she turned green halfway through, but nope—she hit me with the full Tennessee Waterfall. That's dedication."

A really weird sex position where the male, or penetrator, is laying off the edge of the bed so that his penis and torso are still on the bed but shoulders on the ground. The female, or penetrati, inserts the penis into their preference of orifice. The female holds the male with her legs and has full control over how deep of a penetration she would like. The wobbly part is just the dumbass penetrator wobbling on the ground like an asshole.
Guy 1: Yeah I tried doing that waterfall sex move on her but I was so unstable
Guy 2: lol you hit her with the wobbly waterfall

A term for low effort posting karma-farming bots on reddit, who usually have joined the subreddits of r/waterfall and/or r/meirl. The term was (afaik) first seen in r/PeterExplainstheJoke when it was flooded with an influx of low effort "PEEETAH!" (And other variation) posts with memes that spawn the "Bait or Mental Retardartion"Meme
Post title in r/PeterExplainsTheJoke: PETAHHHHH
Comments: "Waterfall bot" "*an actual explanation*" "Bait or Mental Retardation, Call it"
