I've noticed that some people really love to overcomplicate things to seem intellectually superior. For instance, say I somehow dropped a pile of clothes on the ground. They'd then ask me: "When would I stop being a pile? If I keep taking away one article at a time, when would it no longer be a heap?" I'm asking if there's there a word for this needlessly philosophical behavior? Thanks!
The "when-is-a-pile-not-a-pile" question is the famous Paradox of Sorites (sorites being the Greek word for "pile").
Bringing up the paradox (or whatever other obscure issue) on any excuse might be "overintellectualizing" or just "snooty".
