Literally "Good morning a fuck".
An ironic, vulgar salutation to answer to a "Good morning" sometimes used in Italy.
You can hear it mostly at work, early in the morning, from someone especially stressed out.
The intention of those using this expression is to warn their peers about a critical condition, a large workload to be processed soon or already in process, a really bad mood or all the above together.

See cazzo.
