Mess something up. Probably influenced by similar phrases like "monkey around with," "monkey business," and "throw a monkey wrench into." Possibly used as a euphemism for "muck up" by people who consider that already-euphemistic phrase too similar to "fuck up."

The phrase does not have any racial implications, though some have called it a "racist dog-whistle" referring to black people. The dog-whistle metaphor is apt because only a racist who secretly equates monkeys with black people would hear this phrase as having a racial dimension.
"The more you try to do certain things, the more you monkey it up." (Henry Homeyer, "Notes from the Garden," 2003)

"All I did was monkey it up." (filmmaker Kevin Smith, "My Boring-Ass Life," 2007)

"The last thing we need to do is monkey this up by trying to embrace a socialist agenda with huge tax increases and bankrupting the state." (Congressman Ron DeSantis, 2018)

A: "I've never heard the phrase 'monkey something up'."
B: "That's funny because it has more than 400,000 Google hits, even excluding the quote from Ron DeSantis."
A: "You're right. My Internet research shows it's disproportionately used on repair-related forums, like 'I'm betting the alignment shop monkeyed it up' and 'You monkeyed it up with the vise jaws.' This supports the association with 'monkey wrench' and further discredits the claim that 'monkey up' is a racial slur."

A dog whistle a white Republican might use towards a black Democratic opponent while being interviewed on Fox news the day after that black man won his primary, and that electing said black man would be to "monkey this up." Be warned, the white politician may try to deny the obvious connotation by pretending that this is a common idiom, like "monkey around", or "muck it up," but you're smarter than that.
"We have to work hard to make sure we continue Florida going in a good direction... The last thing we need to do is to monkey this up by trying to embrace a socialist agenda with huge tax increases and bankrupting the state." (emphasis on the word "monkey")
