A drinking apparatus, similar to a beer bong for Funneling, made from a pink plastic yard flamingo. The amazing suction-like power of the flamingo neck figuratively shoots the beer down the flambongoer's (also possible to use as noun) throat.
There are various ways to make a Flambongo. The most common method is to cut the head off completely and insert a funnel into the bottom. Another popular method is to simply hack off the entire rear-end of the already-decapitated flamingo.
It's like she can't drink without using a flambongo.
