my additions
This is a great thread.. I have a few to add:
The weave'n'find - the act of pacing from one spot in the yard to another then back to the first, then to another then back to the second, in order to find an appropriate spot to drop the "boxer bomb"
Boxer bomb - that tightly coiled brown substance emited from the end of the boxer, under the "nubbin"
nubbin - small trapdoor-like device used to cover the delicate "brown star" underneath. When a hand comes near the nubbin it seals itself in a "nobody's home" manner locked tighter than a vault.
Brown star - that delightful star not found in the sky, but things far more mystifying seem to come out of, including but not limited to "clinkers", the great stink, the tight coil, "OMG! what did you eat?!"
Clinkers - see cling-ons
OMG! What did you eat?! - what the boxer owner says when instead of being delighted by the tight coil they find a mysterious semi-solid/semi-liquid substance being released from the brown star (usually at the dog park, and usually mommy has to pick it up because daddy says he is going to vomit from the great stink)
The Slap-a-groin - When daddy is sitting very comfortably on the couch and our little boxer friends decided he is too comfortable so with out sign or warning they approach cautiously and slowly, sometimes even doing the military crawl, pop up and with minimal movement merely extend a paw and gently slap daddy in the crown jewels. This usually results in daddy curling up in a tight ball allowing adequate space for the boxer to re-claim a spot on the couch before daddy has recovered.

keep up the great ideas!
