All About that Bass 

Crappy song by Meghan Trainor that's supposedly about how the bass guitar is like the thickness of a song or the bottom, relating to the body like that, yet it doesnt even have a bass drop or any real bass that can be heard over the shitty melody and fake ass lyrics.

It's become popular because it inspires obese woman despite it being a fucking terrible song, even the one singing it is fat, and they even include a fat guy in the video, it looks like she's trying to make fun of herself.

400 pound woman: Yeah i'm all about that bass.
Ideal body weight woman: Shut the fuck up already you're a fucking hippo.

White Bass Choco Splash 

Taking a double dose of Ex-lax after eating Mexican food and waiting until it's unbearable, then punching your girlfriend in the diaphragm, knocking the wind out of her. While she's lying on the floor sucking for air like a fish, unleash the liquidous mess from your anus into her waiting mouth.

Other fish can be used to relate to the person sucking shit matter.
EX) Rainbow Trout for lesbians, Wide Mouth Bass for that annoying chick who won't shut up, etc.

Nick: My girlfriend told everyone my dick was like a pencil with broken lead, so last night we went to On the Border and then I gave her a Whitebass Choco Splash.

Alan: Man, that is brutal!

Gay Bass 

A style of bass guitar that originates from the 80's where the bass run has homosexual tendencies.

Generally, slap bass forms the basis of gay bass and it tends to be short, quick, repetitive runs that are quirky and makes people want to get on the dance floor to perform unorthodox dance moves.

The bassist can complete the 'Gay Bass' look by being shirtless or wearing spandex-like attire.

Luke: 'Is that gay bass in that song?'

Christian: 'That is some hardcore gay bass, I need to bust a move to this. Fancy a trip to the local liberal-minded establishment?'

Luke: 'Sure, as long as there aren't too many Lib Dems in there.'
