do the dew
Drinking something out of a bottle or can without touching it to one's lips; this is accomplished by holding the drink a few inches above one's head, leaning back, and pouring the drink into one's mouth. The term refers to Mountain Dew commercials which show people drinking Mountain Dew out of bottles in this manner ("Do the Dew" is also Mountain Dew's slogan). Doing the dew is employed to avoid sharing germs when sharing a drink; it is also an effective way to spill the drink everywhere and make a mess (see water boarding).
Example:
Chris decided to do the dew to avoid contaminating my soda bottle with his germs; after overdoing it, he choked and spewed it all over Chelsea's face.
