a modernized English contraction effectively combining the words "fucking" and "expensive"; from the dialectical Norwegian root fukka (meaning: to copulate) and the English verb spend; primarily used as an avenue to intensify the perceived value of an already overvalued person, place or thing. mostly used by those too lazy to verbalize both words.
I care deeply about Karen, heck, I've known her since high school...but holy hell, those Manolos are far too fuh'spensive for her very middle-of-the-road income.
A way to express an alternative to "fuck this shit" in the expense of use for bro-dogs/gangsters/and thugs in school. In contrast, the word "fuh" may be subjugated for another slang word used in displeasure.
Teacher: Welcome back! I hope you had a good summer! Take out a sheet of paper and pencil, and write a sentence about what you did this summer!
Thug: Man, I don't wanna do this shi man, fuh dis shi man, dis some bullshi man.
To modify your street car with go-fast race parts or other setups which hold little to no value to the driver, but is good for posing. This is especially popular in the BMW E30 community. Similar to rice, except trying to look like a track rat instead of a street racer.
btw, it can be used sarcastically by people who are actually upgrading their stuff for good reasons in jest towards the people who do it solely for looks.
