1.
A chick who is extra-ordinarily fuckable, a splooge sponge. These sort of chicks attract sexual attention everywhere they go and they love it!
Check out that babe, what a jizz magnet!

2.
One who attracts Jizz in it's many forms. Also, a name like loser, fag, queer, or douche that you want to call someone without calling them a loser, fag, queer, or douche.
Wow, that prick Chad is such a Jizzmagnet.
