Janice was really drunk last night - she went down on me and ended up giving me a radler.

This is when a Female gets so completely and utterly drunk that she does the following:
-Blacks Out
-Hook up with fat/ugly girls
-Fucks random boys in bathrooms or other public venues
-Fail to hook up with hot guys because you pass out on them
-Vomit uncontrollably
-Make loud, boisterous, and thoroughly untruthful claims about your achievements
-Commit yourself to large and utterly hopeless wagers that you have no way of covering
-Bitches out girls she really hates
-Break Things
-Become very angry with inanimate objects, and loudly curse them
-Usually hurts themselves by falling down stairs, face planting or walking into inanimate objects
-Convinces people not to pay their huge bar tabs by claiming "they love me here, they fucking love me here."
-Peeing on the floor
-Removes outlets from walls

Then waking up the next morning completely sober and not recalling one thing that happened.
