When two people mess around on a bed or couch by tickling, poking, pinching, or any manner of playful physical contact in a loving, fun manner.
"So what do you want to do tonight honey?"

"Watch some TV and go to bed, probably."

"Nooo! Why don't we play some cards or *tumble around for a while!"

"Alrighty then, tumbling it is!"

*Alternate forms of Tumbling can be used openly
