A contraction of "fucking" and "expensive" used to denote anything so insanely pricey, usually as to be out of someone's reach. For someone living on a shoestring budget, a brand new
Lexus is fuckspensive. For someone just capable of purchasing and paying for a brand new
Lexus, a multi-engine light sport aircraft
may be considered fuckspensive.
Similar to fucktard, fucktastrophe, fucktastic.
