The excess arm lard on a massive person or commeon folk. When they start to move the lard on their arm starts shimmying like wild tits.
Arnold wanted to holler at lisa, but then she took off her sweater and revealed her tank top. As she was walking the wind and her sudden movements made it clear that she had shimmying arm tits...

Arnold still wanted to holler since he wanted to suck Lisas shimmying arm tits.

Arnold is grimy.
