flabongos are mad easy to make even though it's funny a company is now looking to capitalize on this idea
step 1.
buy plastic flamingo or steal one from someone's lawn
step 2.
cut off part of beak to drink from
step 3.
cut hole in the the flamingo's stomach to pour beer (be careful when using knives)
make sure that you don't cut too much of the beak off otherwise it becomes hard to drink from and find a flamingo with a wide enough neck to help with the flow of beer
step 4.
keep flabongo clean or throw it away because otherwise these things get nasty
