A late teenager who attends a summer camp with the main reason to gain sexual experience from others not associated with their home town school. The term is most often related to females however can also be used for males. ( i.e "Dude lets hit band camp this year and find some cute campsters!" ) The term seems to have began appearing in summer camps around America shortly after the famed line from American Pie; "This one time at band camp...", and continues to gain increased popularity after the release of similar camp movies such as "Fired Up." The word is often used in contrast with cougar
such as; "Man I'm not here looken for any cougar or campster!"
Bro, I met this totally hot campster last night after the movie. I didn't get any sleep.
