Chop Blocking: Cut blocking a player that is already engaged with another player. For example, a defender is engaged above the waist with an offensive lineman, and another offensive lineman comes along and cut blocks him at the same time. Considered the more dirty play, mostly illegal, but also can be legal in certain circumstances in the NFL (I think, don't quote me).
NFL Rules:
LEGAL AND ILLEGAL BLOCK
Article 1 A player of either team may block (obstruct or impede) an opponent at any time, provided that
the act is not:
(a) pass interference;
(b) illegal contact;
© fair catch interference;
(d) clipping against a non-runner;
(e) an illegal chop block;
(f) an illegal crackback block;
(g) an illegal low block during a free kick, scrimmage kick, or after a change of possession;
(h) unnecessary roughness;
(i) roughing the passer;
(j) an illegal cut block;
(k) roughing the kicker;
(l) offensive or defensive holding;
(m) illegal use of hands;
(n) tripping;
(o) illegal peel back block; and
(p) illegal blindside block
If they grab above the waist or engage a player who is otherwise already engaged, it's illegal.
