What a horrible name. Why? Just why? You are putting so much love into something to give it a name that is so bad?
Yeah, I'd reconsider this too. If this sounds too opinionated so far, I'll give you a fact. As a Spanish speaker, this is also a little too close to the word for armpit, and I'd not name my project Armpitt.
It is the Latin for armpit, and related to the (obsolete) English "oxter" for the same.
