Bog
Verb - When a nitro engine stutters upon acceleration. Bogging can be caused by excessive fuel/lubricant in the air and fuel mixture (rich setting) or by too little fuel/lubricant in the mixture (called lean bog).

Lean bog can lead to stalling and overheating, as too little fuel/lubricant is present to prevent friction, heat and wear.
