in-fucking-credible

An expletive-infixed intensification of 'incredible', used to express extreme amazement or disbelief. The obscenity is inserted mid-word through expletive infixation, which follows strict stress-pattern rules in English -- the f-word always lands before the primary stressed syllable. Typically signals genuine awe or shock rather than anger. Tone is almost always positive or stunned. A single word doing extraordinary emotional heavy lifting.

Infuckingcredible is the emphatic, expletive-laced version of incredible — the one you reach for when regular incredible simply doesn't carry enough weight. It's a textbook example of expletive infixation, where a profanity is inserted into the middle of a word for maximum emotional impact. Use it for moments of genuine awe, disbelief, or over-the-top enthusiasm. The game-winning shot, the meal that made you close your eyes, the performance that left the crowd speechless — all legitimate occasions for infuckingcredible.

(slang, vulgar) incredible; unbelievable.
