A catch-22 [beco sem saída] is
a paradoxical situation from which an individual cannot escape
because of contradictory rules. An example would be: To apply for a job, you
need to have a few years of experience. But in order to gain experience, you
need to get a job first.
Catch of the day refers to a fish caught
within the last 72 hours or the fresh fish shelf life (usually 72 hours) that
has not been frozen, canned or otherwise
What's the catch? (Qual é a pegadinha? O que
está por trás?)
"OK, I've seen all the benefits,
but what's the catch?"
"The restaurant is offering free
lunch, but what's the catch?"
