Well, This Is A New One
One of the main things you don’t want happening at a spring break party is to fall asleep first. At least not until your friends are also too drunk. Falling asleep usually means someone is losing an eyebrow or getting their chest hair shaved in a particular pattern.
Some friends may even play the old shaving cream prank. But building a sand mermaid (merman?) around someone is new. The most important thing for this prank is photo proof since it is better to show a picture as an illustration than to merely tell a story about the time you covered your drunk friend in the sand.
