Verb: To unbutton, unfasten, or unbuckle.

This word is completely useless. It sounds ridiculous to say in real life. Why would anyone even bother using such a thing? It's pointless. Any of the above three words for the definition can even fit the damn thing, and it is far more specific.
It's useless. Don't use it.
