A group of feminine males from Central Jersey/Jersey Shore who race bikes, have long, shaggy, unwashed hair, wear jeans tighter than your little sisters and can only beat the shit out of middle schoolers who are half their size. They are known to take homosexual photography and make girlish faces for their myspace pictures. Some of them talk with lisps and wear horrid attire from PacSun and Zumiez, where a large sum of them work. If one gets offended, they try to fight but wind up getting the pathetic shit kicked out of them.
Hey did you see one of the Frope kids making out with another dude last night? He claimed that he was 'drunk'.
A square, someone who is not with it. Combination of "flop + dope" = FLOPE.
In the song "Big Name Button" by the Royal Teens, they sing:
"...you're a flope and you aren't in the club." (if you don't have a big name button, which was all the rage in the late 1950s.)
