Brainal 

the phenomenon whereby the anus possesses it's own brain and makes it's own decisions.

brain + anal = brainal

You are walking home and the urge to shit hits you, the brain in your head tells your anus to tighten and you continue walking. You are doing very well until close to home when all of a sudden you're scrambling for your keys and fumbling to open the door, running to the toilet whilst undoing your pants and just making it in time (or sometimes not making it).

This situation occurs because the brain in your anus overrides the brain in your head. Despite your best efforts to clinch and tighten, your brainal can sense when a toilet is near and immediately starts to open the brown gates.

bottom!blaine 

A canon aspect of Blaine Anderson (from glee)'s sexuality since circa episode 4x16, Feud, but popularized much earlier, thanks to the wonders of Blaine's ass and fanfiction. There are still debates around its canon-hood, probably because its almost too good to be true. We here at UrbanDictionary have patience and sympathy for that. They'll come around.

klainer 1: hey, do you think kurt ever tops blaine?

klainer 2: of course he does, bottom!blaine is canon! didn't you watch feud?

klainer 1: I did, but I thought it meant switch!blaine or versatile!bottom!blaine is canon?

klainer 2: oh honey, that "not really?!" had zero conviction. i betcha also thought we were supposed to believe kurt never picks out his clothes.

klainer 1: wait, so... you really think he wants the D?

klainer 2: he wants the D, and only the D.

Blainers

A loving nickname for Blaine Anderson fangirls. Blaine Anderson is the sex on a stick and sings like a dream, bashful Dalton Academy Warbler who now goes to McKinley High. He is Kurt’s boyfriend. Fangirls who are in love with the out and proud gay Blaine are Blainers.

Could also be used when Blaine does something adorable, or cute, or sweet, or disgusting, or weird, and fangirls are so as;fkdjkl;;k, they can’t think of anything else to say.

Blainers are delusional but perfectly content Tumblr people who worships Blaine Anderson and his magnificent arms.

Blainer 1: Have you seen the photoset of Blaine’s arms after they sing ‘Tonight’? Askdlfj;skdjfl
Blainer 2: OH, BLAINERS.
