A friend from Newgrounds and I have been discussing something; that discussion being that the "V" shape below one's tummy should be called an "addon" (short for "Adonis Belt"), or "addy" if you wanna perhaps be cute about it.
Examples: "Nice addon, bro!", "What a cute addy!"
We have also discussed the possible use of the term "vagabond", as in "vag-a-bond", or "vaggy" with also a hard G when one wishes to be more informal about it.
That is all.
