Senior White Man Present
The guy who gets stuck with the bill. He must be stoically accepting because people would be shocked if the SWMP ever said, "pay your own damn way." Despite his open wallet policy, the SWMP also receives the fewest gifts under the tree or on his birthday. Oftentimes SWMP is "Dad" or "opaw" (grandfather), but an SWMP can be anyone, of any race, or even gender.
Others assume the SWMP always has enough green to pay the freight, even when he's bump ass broke.
The restaurant bill arrives for a bunch of college girls and their moms, one of whom picks it up.
Other Mom: Are you gonna split that up?
Mom: Naw, I got it. I'm the SWMP today. Shit.
