Something large, surprising in it's appearance, or otherwise unique in it's context at the moment. This expletive is used to verbally describe something while having said object or thing being presented to another person or persons. The origination of this term comes from the number fifty being of significant numerical size, it's verbal use as a visualization of something big or unique, and the phonetics of the word itself being somewhat catchy or effective in it's verbal presentation.

A fifty-fifty is an alcoholic beverage containing one half Dubra (about 2 shots worth) and half Hawaiian Punch. This generally fills about half a Solo cup. It's possible to make this with other low-shelf vodka' the point of the 50-50 relationship is that this beverage is only for those with high tolerance for bad alcohol. Two Fifty-Fifties will get a person tipsy. Blame the dirty dubes.
After her second Fifty-fifty, the girl began rolling on the ground in fits of tipsy laughter.
