What are called Death overs or Slog overs in a Cricket match inning?

I have watched cricket for more than 30 years and never heard this term used.

Mythagoman, it may also be noted that it is Lasith Malinga and not Latish Malinga.

Innings not inning.

Bigdaddy, May I point out that not the whole world knows anything about American football and baseball. In fact I'll point out that cricket is far better known by the whole world than American football and baseball.

Player SC, This is probably a term used by the players, rather than the commentators. So the spectators would not necessarily have heard of it.

Let’s have more American football and baseball questions because not the whole world knows anything about cricket. Even the playing field.

Player SC, its between 16 to 20 over or 46 to 50
