This girl told me she bets I have a 3rd grade crush on her.

Maybe SHE has the crush on you and is being playful?

basically you have a silly little crush on her and you probably do things like give her nicknames, playful teasing, playful poking/tickling/hitting/kicking, acting like a retard in front of her...

It probably means that you just like her and won't do anything about it, or that your crush is innocent and it means nothing and that you will get over it really quick.

Think about the crushes we all had in 3rd grade? Nothing ever came of them and no one ever did anything about them and we were over them in like a month and on to the newest thing.

Hmm, I'm confused too. Are you friends with her? If not, then she might have meant it as a bit of a put-down... I.e., that you follow her around like a pet dog and would do stuff like hold hands rather than do more sexual stuff on dates. She might think that you project an immature or too-wholesome image. Other people probably think of you as a nice guy if this is the case.

If you get the feeling that she might have meant it in this way, then she sounds condescending and mean and I would hope that you wouldn't spend a lot of time around her. There are plenty of girls out there who like nice guys! Don't waste your time with someone who is going to disrespect you and make you feel bad!

in 3rd rade when you have a crush,

to get attention, you do things like call her names , pull her hair
and generally be mean to her.


so maybe she is saying you have a 3rd grade crush on her
because you're acting with these mannerisms, and generally being
mean to her, because you like her
