S.C.A.

Strong Critical Atheist- someone who not only doesn't believe in God, they have to argue with everyone who does.

Moreorless as annoying as people who go on about god(s) all the time, mainly because they're so argumentative.

Often found around members of the CU (Christian Union)
CU: 'God is amazing'
S.C.A.: 'Why?'
CU: 'Because He made everything'
S.C.A.: 'No he didn't, you're deranged'

Etc. etc. etc.

S.C.A

Shit Cunt Apprentice. Most Australian people would associate S.C.A with a mediocre tool brand sold by an automotive retail outlet.
But in the tradesman world it's referred to a kid currently under going an apprenticeship who can not do anything right.
