To vomit quickly, and oftentimes secretly, to avoid disclosing the fact that one needed to throw up.

This can be done for a number of reasons:

1. To hide the fact that one is sick
2. To hide the fact that one has had too much to drink at a party
3. To hide the fact that one is throwing up down the back of a friend or enemy's shirt
