When you are feeling extremely horny and you try to hold back laughter, but you fail and end up snorting. Usually resulting in a boner kill.

Get the The Midnight Gigglesmug. The act of shitting yourself while laughing at something. This happens because you were laughing so hard, your anus laughed with you.
Friend 1: 'My little sister told me the Justin Bieber movie was the best experience of her life and started to cry'
Friend 2: 'What did you say?'
Friend 1: 'I started laughing uncontrollably, but then I had a Sphincter Giggle and ran to the bathroom to clean up'
Friend 2: 'OMG I think I just had one too!'
