From my experiences, limited though they may be, "Fucking A" can mean one of three things:
- FUCKING AWESOME. A strongly positive expression. "How was that hockey game?" "Fucking A, man!"
- FUCKING AWFUL. A strongly negative expression. "How was that hockey game?" "Fucking A, man..."
- FUCKING AFFIRMATIVE. A strong expression of agreement. "How was that hockey game? The Reds win again?" "Fucking A, man!"
From what I've heard, the
latter expression was derived from the
military. And believe me, I wouldn't be surprised.
How do I use it? Definition 3. "You're a flaming hypocrite, waverider37." "Fucking A."
