It's actually post-hoc-ergo-propter-hoc or something like that
If you wanna use the latin names it depends on the order of events
it translates to "After this, therefore because of this"
which would be used if someone is saying that x happened after y, therefore y caused x
if they want to say x happened
with y, therefore y caused x, that would be cum hoc ergo propter hoc.
But you sound like a massive dork either way. Just say correlation =/= causation lol
