Spearing

From HallsWiki

An attack made infamous by aaronc3477, spearing is a typically illegal tackle in American football where a player charges at another and drives his helmet into the body. For normal people, this can result in serious injury for both the tackler and the tackled, but aaron's steroid-fueled superpowers apparently prevent him from sustaining damage to his neck and spine. The tackled isn't so fortunate, however.
