Flaco

A Spanish adjective meaning 'skinny' or 'thin' — used as an affectionate nickname for a lean, wiry pet or as a playful contrast for one who is decidedly not.

Flaco is a name with built-in humor and warmth. In Spanish-speaking communities it is often used as an affectionate nickname for someone slim or lanky — but the real comedy comes when it is given to a decidedly round dog. Either way, there's a genuine warmth to it, a familiar casualness that says 'I named you from the heart, not from a list.'
