The act of giving someone a "little something extra" to close a business deal or any other request or arrangement. This generally refers to a handjob, but could include anything up to and including all manner of sexual favours.
My wife wanted some new furniture, and I had said no, but when she closed the deal with a "Carlson Handshake", the next thing you know I am at the store buying a sofa with an extended warranty!
Very common phrase at the University of Minnesota. Refers to anyone studying at the Carlson School of Management. On campus, Douchebag and Carlson are basically synonymous. It is presumed that every Carlson student is a douchebag, so the few who are not must be identified specifically as "not a douchebag" by someone in CLA to be accepted by anyone cool on campus.
A second-tier business school at the University of Minnesota where second-tier douchebags acts as if a 28 score on their ACTs and a B+ in their joke of a Marketing class makes them special. Graduates work in second-tier positions in second-tier companies and uses bullshit words, such as "leverage" or "collateral", to hide the fact that they're not as smart as they think they are.
John, that douchebag over there, graduated from the Carlson School of Management.
I should have known, he was using bullshit words like "collateral" during the 1 o'clock meeting today. Nobody knew what the fuck that asshole was talking about.
