Feaso is Australian professional slang — particularly common in urban planning, property development, and architecture circles — for a feasibility study. It's the kind of breezy shortening that Australians are brilliant at, taking a dry bureaucratic term and giving it personality. If you're in a meeting and someone asks whether the feaso stacks up, they want to know if the project makes financial and practical sense before anyone starts spending serious money.
The developer said he'd greenlight the project once the feaso came back with solid numbers.
Origin: Australian clipping of 'feasibility study', following the common Australian pattern of shortening words and adding a vowel sound (like arvo, servo, rego). Common in planning and property industries. Editorial expansion authored on Slangora.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- fasho59%
Slang for "for sure" — an emphatic yes, an agreement, a confirmation delivered with zero hesitation. It's hip-hop and AAVE-rooted, compact and confident. You say fasho when someone asks if you're coming through, if you're down for something, or to seal a plan. It's also crept into general Gen Z usage beyond its original community. Occasionally it also appears as a shorthand for "fascist" in political slang, but that usage is far less common.
- deso57%
Australian slang for the designated driver — the person in the group who volunteers (or draws the short straw) to stay sober and drive everyone else home safely after a night of drinking. Short for 'designated driver' via 'desig' to 'deso,' it's a very Australian compression. Being the deso earns you social credit and the eternal gratitude of your mates, even if it means a night of sipping lemonade while everyone else gets loose.
- fisho55%
Australian slang with a double life: it can refer to a fisherman who actually catches fish, or to a fishmonger who sells them — context usually makes it clear. It also lives on as the traditional cry of a fish seller at markets, the local equivalent of 'Fresh fish here!' The '-o' suffix is quintessentially Australian, applied to all kinds of occupations and words (tradie, garbo, smoko) to create casual, egalitarian nicknames. Fisho is warm and familiar, evoking weekend fishing trips, seafood markets, and coastal Australian life.
