look up any word, like plopping:
 
1.
2k
The most painful & stressful period of minutes where a rower places oneself on the erg and is determined to finish in the lowest time possible. A rower pulls the distance of 2000 kilometers, hence the name 2k.Extreme amounts of water must be consumed before the painful experience to hydrate the mussels. Talk about lactic acid, your body is full of it and crying out for help. During this time period, you will cry, scream, sweat, and be full of pain. However, the dreaded 2k may determine your seating position, so there is no time for slacking.

2k
The most accurate test of human strength and endurance-halfway between a sprint and a long distance piece: a 2000 meter row. This way, your lungs are starved for oxegen, and your mucles burn too.
