Mikeing is a very lame attempt at a comeback developed by a guy named "Mike" who thinks hes clever but fails on all levels to deliver a comeback that makes an ounce of sense or truth. In turn he will make up things to 'burn' people with and it never quite works out the way he intended it to.
He thought mikeing her would do it but he couldn't think of anything factual to use so he made up something stupid instead.
To dry hump an inflatable whale.
My neighbor was mikeing in my pool.
