I have different crushes for different reasons. I have safe crushes and not so safe ones.
I crush, Grenade, because she is mean to me and I sort of like it. (I also have a couples crush on Stargazingboi and Grenade).
I crush, Katniss, because she is intelligent, witty and funny. She can also find a picture for any occasion.
I crush, Sweet Bliss, because she is blissfully sweet and always has something nice to say and she is also funny.
I crush, Huge Smile, because she tells wonderful stories and is adorable.
There are women that I crush that I have never communicated with but their posts make me literally laugh out loud.
I can't name them all, but the common "thread" is I love to laugh and I love a great sense of humor. I crush the hell out of funny.
