Daülk 

A Daülk is a type of Australian pale ale when drank from a can. But is also a slang name given to a bigger than average penis.

“On the sixth day, God created Adam and Eve, he said “eat all the fruit you want, except for the forbidden apple... and also... don’t step on my Daülk...” Adam didn’t listen, and stepped on God’s Daülk.... God was furious!
