Runnin' the show

An expression used to express total dominance and/or superior skill over a particular event or activity. Used often in sporting events, but also used to express authority over others.

Man, Paul's been runnin' the show all season!

I just got a thousand kill streak again! I'm runnin' the show!

Okay Greg, I'm runnin' the show tonight, so go make me a sandwich.
