ARM PARTY- VIA URBAN DICTIONARY

When somebody (usually/hopefully a girl) wears a bunch of different bracelets on the same arm, sometimes using many bright colors or different materials/metals is called an arm party. The more the merrier!
that girl with the huge arm party thinks she’s ke$ha, her bracelets weigh more than she does!
