Completely killing it at work. Getting shit done. This term is specifically used a lot in the tech/design/creative field. Can be used almost interchangeably with Charlie Sheen-esque "WINNING!" but more about getting things accomplished. Almost could be similar context of "pwning" but less about crushing the competition and more about doing great work.
Boss: How's it going today? Employee: Dominating!
