elephant's instep 

The best of something, something that is excellent. Originally coined as a sarcastic rejoinder to bee's knees

"How are you?"

"Oh, I'm the bee's knees. The elephant's instep, if you would."

"Jolly good!"

"Right-oh, let us giggle uncontrollably while eating these buttered crumpets!"

"Ah HA ha-ha-ha-ha-HA!"

instupituous

this neologism stems from the seminal hip-hop release deltron 3030 by the group of the same name (dan the automator, del tha funkee homosapien, kid koala), specifically track 3, "the fantabulous rap extravaganza."

usage: instupituous refers to something that is beyond dope, possibly interspatial, maybe boasting jet propulsion or at least better rhymes than any you've ever heard, including the time your cousin d-pennyweight busted freestyles for an hour and a half while you and your girl jammed to it by a bonfire on the beach out of the back of a 1967 chevy nova.

be there for the rap battle
it's going to be interspectacular!
fantabulous!
it'll blow your socks off
it's one of those things where machine vs. man
man vs. woman
woman vs. your mother
be there intergalactic rap battle,
it's instupituous!

Instapoet 

Hipsters who can not get published for their writing and so they turn to Instagram to try and be known.

Typically seen with beard, Beanies, and Alcohol.

It is impossible for them to get dates and yet they continue to write about 'love' as if they experienced it.

Also, known as whiny douchebags.

That Instapoet ACTUALLY thinks he can write?

If the river runs red take the dirt track instead 

If one's girlfriend is on a period one should stick one's cock up her ass instead

When a man fucks his lady up the ass because she is on her periods to avoid a bloodstained cock
