instafriend 

When you meet gregarious friends of a friend of yours and they automatically become your friends, too. While there's potential for meaningful relationships, instafriends usually remain cheerfully superficial.

"I went to a party with Frank, he introduced me to Sally, Joe, and Bob. We all exchanged numbers, yay, three instafriends!"

Insta-friend 

The most annoying people in existence and usually leave you guilt-ridden when you get rid of them. Usually are people who you have no interest in gaining any form of relationship with, but one friendly remark and you have a new buddy.

EXAMPLE 1

Terry: *Sitting on the bus*

Hoit: Hey Terry, nice shoes

Terry: Uh, yeah...thanks...

Hoit: OH MY GOD we are exactly alike

Terry thinks: Goddammit insta-friend...

EXAMPLE 2:

Jack: Hey Josh, do these stick-

Josh: STFU GTFO

Jame: Hey man, wtf that was harsh

Josh: I don't need another insta-friend
