Slang: Too hot to handle

Definition: Difficult; hard to deal with; controversial.

Etymology: 'Too hot to handle' comes from baseball, referring to a ball hit so hard that it can't be caught. In this phrase, 'hot' means 'lively' or 'powerful', and 'handle' means 'take care of' or 'pick up'. The phrase is now used to describe any situation that is hard to deal with or problematic.
