instazone

A guy who is used solely by his girlfriend as her personal Instagram photographer.

Often seen holding a camera while his girlfriend strikes numerous poses and tells him which shots to take.

The next step from a boyfriend whose girlfriend is constantly taking selfies.

John came back from holiday having been totally instazoned by his girlfriend. He spent more time looking at her through a camera than actually enjoying himself.

I think I’m in the instazone. All she wants is more pictures.

Instadouche 

This occurs during the lake season while a girl, preferably in a small bikini, goes tubing. The previously mentioned girl is sitting up right and as the boat goes around a turn one leg slips off the side into the water and the other stays on giving 30 mph water a straight shot at her vagina, instantly cleaning it out of all dirtyness.

"Dude, Sam, did you see Kaitlyn get that instadouche at the lake last weekend?"

"Yeah I might actually eat her out now."
