romp on (someone or something)
1. To utterly dominate someone or some team in a competition. The Colts were romping on the other team at halftime, up 45 to 3. I knew I stood no chance of winning against him, so my goal was simply not to let him romp on me for the entire match.
2. To go off-roading or trail-riding on something, such as a mountain bike, dirt bike, ATV, etc. You've been romping on this bike all summer long and haven't done any maintenance on it. No wonder it's ready to fall apart! I love going out to my cousins' house and romping on their four-wheelers around the fields behind their house.
