One of the more obscure Aussie slang terms used in predominantly slapstick situations usually involving alcohol. When your mate goes to the bar to grab the fifth round of drinks and smashes a glass on his way back, yell "TAXI!"
It's a light-hearted, humorous expression which implies that the person who smashed the glass had a little bit too much to drink and needs a taxi/uber/ride home. You can make the situation even funnier by actually chucking your mate in a taxi just for shits and giggles.
1. (In Pakistan) Prostitute
2. (In Pakistan) A woman of bad character or famous for having questionable relations with many men. An adulterous woman.
(Originated from the reference to real taxi cabs which always have different riders everyday.)
