oh, okay, at my gym this is muffling, pinning, folding, and trapping. Boxing has so many nuances that all have so many different names, that it is often hard to keep them all in line. I watched Foreman v. ****ey last night, and you can see Foreman muffling shots with his right hand. Half way through his cross guard setup, he would push at the opponents lead hand and muffle the jab, then cover up. The folding happens naturally in the cross arm guard, so it seems, as punches that fly over the lock can be shoved further out of the way during slips which can set up the hooks/uppers.
