When one person goes in for a fist bump and the other greets that fist bump with an open palm.

This can either be on purpose or by accident depending on the situation,
"Dude i totally went to fist bump Mark and the jerk palm fisted me."

"I think he thinks i'm a poser.."

or

Guy 1: "I went to fist bump Joe and he went to give me a high five - Total Palm Fisting "

Guy 2: "Man he never knows whats going but hey at least he tries hard"

Guy 1: "Yeah nice guy, tries hard, bottom third.."

Guy 2: "Well he is good for a laugh.."

Guy 1: "Yeah and his sister is Hot :) "
