The feeling of an approaching sneeze, but having no release
I was excited for my oncming sneeze, but was let down, as it was only a snease.
Person one:My nose is about to nut.
Person two:You mean snease?
Sexual act of expelling air from your nose into a vagina or dick hole.
My girlfriend asked to try a new sexual position. While eating her out, I couldn't deny the chance to try sneasing right into her vagina.
I'm single now.
