a hot chick (rig) that is recently discovered but does not belong to the so called 'popular' group. it refers to hot/fit chicks with a good body that float with the wrong crowd, that just dont match the rest of their group because they are a rigoon.
tom: oi mate, how hot is that chick sitting over there
ben: yeah mate shes so fit. but ive never seen before, does she hang out with the sluts and popular girls?
