Chundering up large amounts of Stella Artois (a Belgian beer), to give the impression of a waterfall

A Belgian Waterfall is when a guy ejaculates in his partners mouth then tickles them intensly to the point that the semen shoots out their nose. The same way that orange juice comes out your nose when you laugh.
Alex Willard received a belgian waterfall from Micho the other night and had to go get surgery on his nose.
