Isaac 

to pull an Isaac, is when someone wimps out of physical contact with a super hot sexy girl, by laughing and pulling away. Maybe an early sign of homosexuality or simply pre-maturely ejaculating

-"Dude, you should totally of gone in for a kiss! Why did you pull an Isaac?!"

-"Damn, that girl is SLAMMIN' I would NEVER pull an Isaac on her!"

The type of dude who will fuck you over. The dude will "help" your best friend but really cheat on you. Its the type of dude who plays with ya & other girls. He's the worst kinda dude you will ever meet & you'll be able to tell he's an Isaac bc he's so freaking ugly,, he looks like Slender Man. Anyways don't date him you'll get your heat broken.
