Verbal Strikeout
When somebody tries to either: 

a. Tell a story
b. Say a sentence
c. Get a point across

but has to restart at least 3 times, you can call for a quick end to their speech by shouting "VERBAL STRIKEOUT". Three strikes you're out. The conversation must then make a complete shift and move on to another topic.
Guy 1:  Hey man, last night was crazy, I was at a frat house and- well I was at my FRIENDS frat house then- but wait hold up- It might have been two days ago-

Guy 2: *rudely interrupts* YOU'RE OUT! Shut up now.

Guy 1: Wtf bro?

Guy 2: Verbal strikeout, duh.
