Oral sex as a birthday present.

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. =)

A Birthday Sandwich is a sexual innuendo for a man laying on his back, a woman straddling him, and another man filling the final hole of said woman. Said sandwich must be received on birthday.
