Getting a free hand job from a backseat buddy while you're stuck in front like a clueless idiot.

I got a hitchhiker's tickle when my buddy in the back started jerking off while I was trying to find my phone.

Front seat guy got a tickle from the backseat legend while I was yelling at the GPS.

My friend got a tickle from the guy behind him while I was trying to ignore the smell of his farts.
