instafooled 

The term used when your Instagram crush doesn't look like his/her picture in real life. The frequent use of filters and deceptive angles may cause you to believe they're a certified 10 on the scale, but in real life, the way the light hits their face doesn't do them any justice.

Merhawit: I met my Instagram crush last night, but he didn't look like ANY of his pictures :(

Natanya: Damn, girl, you were instafooled!
