A deragatory word synonymous with red-heads. Similar to calling black people niggers, chinese chinks, and other orientals gooks. Used by those that cannot think up an insult on their own, therefore they say this, and then others giggle hysterically.
All people with arps have HUGE dicks.

You yell ARPS whenever a readhead is nearby. It means All Red Pubes.
Fuck you, ARPS is owned by the La Salle boys.

My brother started developing an arp when he was 13.
