The name given for the motion natural breasts make during a woman's movement, usually while involved in a sexual act; originating from the term "Waterbed Motion"

The rhythmic movements of a woman's body will be mimiced by the movement of her chest in a way that is almost as hypnotic as a lavalamp. Women that have undergone implant surgery to make their breasts unnecessarily large (boob job) will usually lose The Wabum Effect

Without naming it specifically, Robin Williams helped to define the Wabum Effect by saying "Fake tits are like nazis; they don't laugh, they don't dance, it's just HU-YEAH! I'M WALKING HERE!"
Man 1: Look at the rack on her!
Man 2: Nah, not my style. They're totally fake, I like a girls tits to wabum, it's just sexier when they move like that!
Man 1: I don't care if they wabum or not!
Man 2: Then go for it!

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
