When you see somebody really and you dont really talk to them or only see them in the hall or shopping mall
lilly: Omg look at him
Jess: do you have a crush on him?
lilly: no I don't think so, just a hall crush
The person you had a crush on when you were very young
I remember watching Get Smart as a three year old. Agent 99 was my "toddler crush".
A crush on someone from a previous decade or historical era, regardless of whether they are still alive today - Such a celebrity when they were younger in the 70's, or famous historical figure.
I have such a retro-crush on 1980's Harrison Ford.
When an adult has a strong fondness or admiration for a child they know but aren't related to, like a daughter's friend. Analogous to a boy crush or a girl crush, it isn't necessarily romantic or sexual in any way.
A part of me really wanted to get to know this child better but I was certain that people would assume a child crush meant more than it really does.
An advanced crush is what two people would label their relationship when not yet a "thing" or they are not yet a couple, but they are not "just friends"
Bob and mary hang out all the time and text each other all the time. They cuddle and kiss but they're not dating. They also deny that they have "a thing" together. They gotta have an advanced crush
An instantaneous crush on more girls at the same time, but only works when they are both together.
"Oh man, I have the biggest gang crush on Jessie and Morgan"
"Bradley is Gang Crushing after seeing that post of Jessie and Jamie tripin'"
