I actually try to not do that now. As they say, programming is the art of naming and I think forcing myself to think about what a variable is (and then using that name) leads to better outcomes.

Agree for throwaway work it may not matter but I try to keep myself disciplined anyway. A good example is say I am doing an advent of code and the temptation is to treat it as throw away code. But the reality is, sometimes I put it down and come back to it, and having variables like fart doesn't really help snap back into the context.

Not saying this is an absolute but I find it a general rule of thumb for myself
