Smilkshake

A blended mixture of smegma and milk. Similar to the consistency of a milkshake (hench the name).

In the fraternity's new hazing tradition, recruits were forced to drink smilkshakes from the vaginas of nasty old women.

Stiltshake

This is a bespoke milkshake - one reserved only for those of society's highest ranks. A soothing blend of Derby's most gruesome, gone-off phlegmy cheese combined with the children's toenails found in Sneinton's grimiest orphanages.

"Waag, did you try a dollop of that new stilton milkshake from CookieShake?"
"Yeah man, that Stiltshake tastes gruesome"
