bubble
n.— «In NFL scouting parlance it is referred to as a “bubble.” You and I call it a butt or backside or rump. If you’re an NFL lineman, the bigger the bubble, the better, because it makes you tougher to move. Eagles defensive tackle Corey Simon’s bubble is, for lack of a better word, significant.» —“Smith believes 49ers made a smart choice” by Paul Domowitch Philadelphia Inquirer (Pa.) Apr. 25, 2005.
