Insta-Creep 

An automatic designation for any individual of upstanding social or economic status, regardless of age, who somehow chooses to romantically engage another who is younger by 30 years or more.

Oh, that's just Nas-T...he's got to be at least 35 years younger; not only does she probably taste like a prune-pit--that makes him an Insta-Creep! Unless she's loaded, in which case it's totally cool...

When you add your friend's Instagram story to your Instagram story, and your friend adds your Instagram-story-addition to their Instagram story, creating a possible infinite loop of Instagram stories.

Man, this chick's instaception is messing with me--I don't know whose story this is anymore!

Instacrap 

The vast plethora of instant and frozen meals and other foodstuffs, loaded full of chemicals and salt, made from the reconstituted offcuts of various animals and packaged as a delicious, convenient alternative to proper cooking.

That woman in front of me at the checkout has a whole trolley load of instacrap.
