Yeah, there are some that seem to come with a built-in eyeroll. "Snack" still amuses me but I've always been iffy on some of the other Snape ones, despite their prevalence. "Sn" isn't exactly a graceful consonant (though it was interesting to learn there was an actual named reason it tends to dominate in smush names formed from it), so I've always preferred to say "Severus/Lily" rather than any of the smush possibilities, like Snily, Snevans, or even Severily.
