bumpchuck 

(v) a hug/push that gets out of control during foreplay, often resulting in broken porcelain objects.

While preparing for fornication, to liven things up one may consider bumpchucking their large, naked, hairy, drunken mate into a porcelain object resulting in $500.00 worth of hotel damages and 3 inches of flooded bathroom floor.
