Get the ANTHRAX mug.
1. An 80s heavy/thrash metal band. Part of the Big 4 of Thrash, consisting of them, Metallica, Megadeth, and Slayer. Did some stuff with Public Enemy that many people liked, but i personally hated. Overall, Antrhax is a great thrash metal band that gives you a Fistful of Metal! (Anthrax fans should get that)

2. A white powder, deadly when inhaled. Often used by terrorists in envelopes so, when opened, the opener would be doomed.
1. Anthrax's song Madhouse is one of my favorite songs.

2. Oh, mails here! Let's see here...goddamit...

The act of covertly fucking someone over without them knowing it.
As I took a bite into the Big Mac and tasted brownie, I knew I had been totally anthraxed.

Get the ANTHRAXed mug.
one of the most amazing metal bands ever, started in the early 80's, and one of the only one's that have stayed true to metal, each one of their albums have its own distinct sound that still manages to be diverse

the original lineup had joey belladonna as the lead singer but in the early 90's belladonna was replaced with john bush, producing some of the best anthrax albums to date, namely We've Come For You All which had Dimebag playing lead on two of the songs, one of the best and most underrated albums to come out in the past five years

john bush was recently replaced for joey belladonna as the lead singer and anthrax is doing a "reunion" tour although i hope that john bush soon rejoins the band again as the music produced during the john bush era was superior to and more mature than earlier anthrax albums
I hope Anthrax comes to their senses soon and gets rid of Belladonna for Bush.
