A PONIS is the long, stringy ponytail found on (usually) older men, aging hippy types, typically with thinning hair (or just about NO hair), where each existing strand is lovingly washed and tended so that it can be carefully included in the skinny ponis, the purpose of which is to show that the bearer is still hip, still cool, and maybe still a bit virile. A ponis rarely looks good, often looks ratty, and should usually be CUT OFF!!
