Short for Beelzebub, AKA the Devil or Satan, according to a song by Stephen Lynch titled by the same name.

Get the Beelz mug.
verb, intransitive. To react or act in a highly agitated manner. To freak out. N.B. The word does not always convey a negative connotation (see examples)

beelzes, beelzed, beelzing

From the old Hebrew Baalzabub, or other Semitic etymology such as Baalzebul. The rough translation of the Hebrew is Lord of the Fly whereas the other Semitic Baalzebul translates as Lord Prince. The modern definition of the extended word Beelzebub is Satan, or the Devil.

Beelz derived from an observation that "if Beelzebub showed up, you'd really beelz out!" Since "beelz out" was already similar to freak out (see above), the out was dropped.

Etymology of the word beelz dates to the mid 1980's, possibly the late summer of 1987. The word is purported to have first been uttered in Canada, somewhere north of Detroit along Lake Huron. Possibilities include the cities of Wallaceburg, Chatham, Grand Bend, or most likely, Sarnia, the most populous of these cities.

To freak out, often in a comical manner.

Etymology: From Baal, one of the false gods of the Old Testament, and from, later, Beelzebub. First used as a synonym for freak out around 1980 in Southwestern Ontario, possibly in the area of Sarnia, a border city of some 75000 people.
