Pronunciation: [dˈuː dˈɛθ] (IPA) 
The correct spelling of "do death" is actually "to death," which means to the point of death or extreme exhaustion. The "o" in "do" is often heard due to the regional or dialectical differences in pronunciation. However, in standard English, the correct spelling is with a "t," represented by the IPA symbol /t/. So next time, make sure to spell it correctly as "to death" to avoid any miscommunications or confusion.
"Do death" is a colloquial phrase in English that typically means to exhaustively perform a particular task or activity to a point of extreme and complete exhaustion or fatigue. The phrase is often used to describe an action that is done repeatedly or persistently until one is thoroughly worn out or unable to go on. The term "do death" is a figurative expression, and it does not refer to any literal physical harm or fatality.
The word "do" in this context means to carry out or execute an action, usually with great effort or determination. The word "death" is used metaphorically to emphasize the intensity or extreme degree of exhaustion that is felt after engaging in a certain activity or undertaking a task for an extended period.
As an example, one might say "I played basketball for hours yesterday, and I ran so much that I ran myself to death." In this case, the individual is emphasizing that they ran so intensely and for such a long duration that they felt utterly exhausted and could not continue.
Therefore, the term "do death" serves as an idiomatic expression to highlight the level of fervor and dedication put into an activity, often resulting in utter exhaustion or complete fatigue.
