In the game of beer pong when someone makes it into a cup that the opposing team is drinking out of, or when the opposing forgets to pull a cup and then the cup is made again.

When someone gets it in a death cup (being drank out of cup, or in a forgotten cup), the game is over and whoever made it in wins.
Guy: they both made it in the same cup, isn't that death cup?

Girl: No, you are wrong. Death cup is when they make it into a cup that the other team is drinking out of, or that they have forgotten to pull.

Guy: Oh yes, you are right, I am wrong.

A death cup refers to the rule in a popular drinking game whereby, if an opposing player sinks a ping pong ball into your “death cup” the game is over immediately, with no chance of rebuttal from the opposing team.

When a partner feels as though the relationship must end, after constant arguing and break-ups, they may resort to the option of "Death Cupping." This will result in the sudden and irrevocable end of a relationship.

Sarah : "Bro... sounds like he death cupped you. You're probably better off without him, let that toxic relationship go."

Slappy Cup Death Round is an intense round of the drinking game Slappy Cup. Find an ally, replace the typically plastic cups with glassware, and get to slapping.

Tips: Wear closed toes shoes, don't expect any of the glassware to survive the round, and seek out a homeless person in the ally to record because as you can imagine, death rounds are epic. Be kind, pick up the pieces.
