Any sexual act occuring in any Bathtub or swimming pool. Used on The Cosby Show in the 1980's when Cliff and Clair wanted to go upstairs and bang in the shower "Come on dear, lets take a Huxtable swimming lesson"
Guy 1: There is a lot of banging noise coming from the bathroom. Guy 2: Yeah Jeff and Sarah are taking a Huxtable swimming lesson

The two or three days a year when the water temperatures peak above 10 degree centigrades, is called 'the Norwegian swimming window', or simply the 'swimming weekend' by Norwegians.
Bjørn: Wow, radio said the temperature in the river is 11 today, wanna go swimming?
Arne: Sure mate, who doesn't wanna go swim during the Norwegian swimming window?
Bjørn: You've got a point, let's call in Petter, Knut, Bjarne, Kjell and Fridtjof too.

very big, steep, and annoying hill that kids that go to the summer camp, Usdan, have to walk up to get to the pools. However, when going down the hill it is very hard to walk normal speed, and you feel like you're going to fall.
Ugh! I hate going up the usdan swim hill. They should knock it down and build elevators, jetpacks, water slides..
