When you leave work with the sole purpose of killing time and walking to get a snack. Also known as a Snack Walk.
Fuck this report. I'm starving. Snalk anyone?
When you are talking to someone, nearing the end of the sentance or thought, and a sneeze comes on. Instead of just excusing yourself and taking a second for the sneeze, you continue talking thinking you can make it to the end of your comment before the sneeze overcomes you; You were wrong, you have just snalked. Sneezed while talking.
She was telling me this story and then just snalked all over my face cause she was too excited to stop the story.
