look up any word, like sweetest day:
 
1.
an amazing prank in which an un-named friend blindfolds an erin, lathers her in ketchup, and makes her sit with him/her in a jaccuzzi with a sailor hat on.
(or it can just mean sex with an erin who has a sailor hat on)

lots of fun. =)
kelsey: so how did erins birthday turn out?
levi: pretty well, it took forever getting the hat on though.
