Rollercoastering 

When a couple sits on the same side of a booth at a restaurant with no one sitting across from them.

I observed Samantha and Philip rollercoastering at the sushi restaurant on Saturday.

Rollercoastering 

When you’re high, but it keeps coming in waves, so you’re super high, but then suddenly feel sober and it rollercoasters back and forth.

I want to smoke more because I feel sober, but I’m worried that I’m just rollercoastering

Rollercoasting

While a picture is being taken, you throw your hands up and look excited in order to simulate being on a roller coaster, thus both ruining and enhancing the picture. Roller coasting works best if the people in the front of the picture do not know it's being done behind them. The more people roller coasting in the same photo the funnier it will be.

The rollercoast can be made exponentially more hilarious by adding more people, having everyone lean in the same direction, and having people organized in rows of two or four, to simulate an actual roller coaster. The effect is weakened significantly by the participants actually being on a roller coaster.

Everyone get into pairs and look for people taking pictures tonight. We're gonna do some serious rollercoasting
