Exclamatory acronym using the first letter of each word in the phrase “balls in my face.” As can be deduced from the literal meaning of the idiom, BIMF is most fittingly used to express extreme distress, often at the unfairness and unwanted strife resulting from a punishment or an unexpectedly and unforeseeably agonizing incident, and inherently compares the painful and undesirable ramifications of the experience metaphorically to having a huge set of hairy testicles plastered against one’s face.
