When a big-time consultant physically rolls his office chair into your cube (or office) to annoy you with something pointless. The result is usually a feeling of anger and physical harm is entirely possible. This is different from a regular "sidle" which does not include a chair, but rather where the BTC (big time consultant) lingers annoyingly for no reason. Think of Lumbergh in "Office Space" rolling up "Peter... what's happening!"
"That fucking douchebag consultant keeps roll-sidling me all fucking day.... can't someone give that guy something to do! How many times is he gonna come over and tell me the stories about his old job?"
