low crawl

When someone is or acts like your friend, but secretly tries to steal your girl(s).

From the military tactic where soldiers lay low and slowly crawl inch-by-inch, then pop up out of nowhere and stab 'em in the back.

These guys can't pull any girls themselves so they just hang around me and try to low crawl me.

I don't have any good wingmen, they all low crawl me as soon as I talk to a girl.
