one who sits on their scateboard on the curb watching their friends do tricks. Similar to a poser or wannabe. Usually the kid who wants to ride scateboards but truelly lacks style, cordination, and courage. When invited to participate the individual will always have hurt something recently ie knee, ankle, has a headache, or whatever.
Man, Leonce is nothing but a curb camper! He never pulls any tricks and always complains that he hurt his ankle, knee or something!
