So I looked up the actual definition of having a 'catholic taste', and it appears that I'd gathered the wrong contextual meaning for it.
(especially of a person's tastes) including a wide variety of things; all-embracing.
I'd like to know the/a descriptor for having monogamous, boring, standard, reliable, consistent, never-varying, rigid, limited, what-you're-already-familiar-with, unadventurous, self-consistent, taste.
Obviously, I could use one of those words, but I'd liked the flavor of 'catholic'. I'd also wanted a word which implied many/all of those things together (in varying degrees), without requiring a couple of sentences of explanation.
He had catholic tastes in sandwiches.
He had catholic tastes in movies.
He had catholic tastes in girlfriends.
Conservative, moderate, and conformist as substitutes only work for some varieties of a-catholic tastes:
He had an acatholic taste in girlfriends; namely blonde, blue-eyed, corn-fed wholesome Midwestern girls.
Doesn't work out so well, when you say:
He had an acatholic taste in girlfriends; namely pierced, heavily tattooed, emo girls with radically dyed hair.
Which is not a standard, conservative, or moderate type of taste — but it is consistent, reliable, and unvarying (in this description). Getting the second guy a date with Sienna Miller would only work for someone with catholic tastes, not someone with a [blank] taste.
But, I'd like a go-to word, that I could use for both guys.
Or, example-wise: sandwiches. movies (scathing expose documentaries vs. summer blockblusters)
