This does not cover trivial death penalties, such as in deathmatch games losing the weapons that you collected 5 seconds ago and can collect them again in the next ~10 seconds or so. Nor does this cover negative score, or loss of lives.

However, non-trivial lost equipment, xp gain penalty for a significant amount of time, a significant xp loss (even character level loss), an artificial detriment (lowered stats for a significant amount of time), etc. do count.
