A work projecting outward from the main inclosure of a fortification, consisting of two faces and two flanks, and so constructed that it is able to defend by a flanking fire the adjacent curtain, or wall which extends from one bastion to another. Two adjacent bastions are connected by the curtain, which joins the flank of one with the adjacent flank of the other. The distance between the flanks of a bastion is called the gorge.

  • Bam to behold, a public bulletin board, built of both brilliance and barbarity by bastards with boners. This bastion, no mere bulwark of boredom, is a brutal barrage of blistering bullshit, barely benevolent... but behind the bigotry and boobs, beyond the bitter broadcasts of bragging buffoons: here be the body politic. A brotherhood of blasphemy, blessed with more balls than brains, battling the bland, the bogus, the benign. Bedlam? Bring it on. But I babble... better to be brief.

    You may call me /b/.
