From your friend's account,
LOMCEVAK, it
might be indicative of an aircraft carrying out an S-turn (but banking >30 degrees to stay on the LLZ), with a steep nose down attitude to dive off height, then levelling off and chucking the gear out to slow down to flap extend speed, before catching the glide slope.
But just a guess.
Nothing wrong with going around these days is there?
