To Urinate. Specifically (but not exclusively) in a urinal.

Origin: Certain urinal drains bear an uncanny resemblance to classic comic strip character Ziggy staring up at you. (two beady eye and a giant nose)
If the drain is backed up, or you have a exceptionally robust stream, it is possible to completely submerge the "nose" and therefore "Drown Ziggy"
As nothing good ever happens to Ziggy, it is rather fitting.

March 15th is the official cum drowning awarness day. We have had too many cases where ignorant boys and men don't realize that it's possible to drown themselves in their own cum. It is only acceptable to celebrate this day to remember the victims of cum drowning as well as spread awarness.

To drink heavily; To binge drink.

Infamous drinking game that is typically held in frats nation wide. The rules are simple, the first person to need a stomach pump loses not only the game and their dignity but also the privilege of having a working liver. This should not be confused with a drowning liver.

TERRIBLE!
BAD!
horrible!

When some has no banter and all of the moisture is taken from the air

It is when you take you girlfriend on vacation in south florida. the two of you have a nice dinner and you end the night with sex. as you are about to cum you hold her nose and begin to strangle her and right before you cum, you force your dick in her mouth so she is forced to swallow every drop as she gasps for air. (usually white women will let you do this more than once.)
