trunk out

To dance spastically or as if in seizure in the trunk or boot of a car. To get your groove thing on baggagairily.

Yo Kenny, don't trunk out, you're shaking my geo.

trunked out

When someone has had so much anal sex that their anus resembles an elephant's trunk.

She is so trunked out you could jump rope with it!
