You actually used the phrase "Do you want a punch in the kisser?" so I'm glad it went up in smoke.
Accidently spitting when you talk or someone doing it to. You both know what happened, yet neither of you says anything.
Also, the supermarket... bumping into someone you know. You have a talk for 5-10 minutes and then part ways... just to bump into each other in the next isle. Awkward.
EDIT: Right-Track
