Manguin 

a creature who's sole purpose, it claims, is to 'help you help yourself' however frequently finds himself in situations where he is the one in dire straits. Commonly found in the headlock position of an unimpressed bouncer, his travels take him to populated student haunts across London where he takes it upon himself to get ridiculously drunk and make absurd hand gestures to the song 'mr brightside'. Usually found in trackpants and hoodie but occasionally known to gallavant around in a bright blue dressing gown this creature is harmless and should not be taken seriously at any point.

'Oh dear, Manguin is in a bad shape'

Monguiste

A contextual placeholder that is used to describe a specific lifestyle or essence of sexual innuendo that highlights dirty behaviour with a side of romantic lust.

Oh mommy, you know I love mac and cheese for dinner, let me repay you with a lick of the monguiste.

I walked in on my mom and dad watching some porn, and i heard my mom say oh my god my monguiste is dripping. I cant believe that whole thing fit.

When you have a fever, and your step mom walks in with a thong and spiked black dildo in hand, and says let me fix your monguiste.

Monging Out 

Basically - Zoning out, going into a daydream like state and you can't help but do so. When your eyes become fuzzy and you love to stare at an object in front of your eyes.

It's both a natural thing that happens and can also be caused by smoking weed.

"I can't stop monging out!"
