The non-premeditated and irreversible state of being a family within a band. Especially in marching band. Bamilies often times form much stronger internal bonds and abnormal (in some cases bizarre) attachments than the traditional marching band; as a result they are much more desirable than the traditional marching band.
Crowd: Woah, who's that big band?
Band parent: What band? Oh, you mean that super awesome bunch from Kingston?
Crowd: They're awesome!
Band parent: That's no band; that's a bamily!
Half way between drunk and buzzed. Coined circa 1995 in Erie, PA. Derived from the two last names of those who were drunk and buzzed. A third individual described himself as "barmillen," not yet drunk, but way past buzzed.
I was sitting in Gazzo's basement deciding whether to have another beer or not. Since I was only barmillen, I thought I could afford to have another.
