The terms "ולא היא" ("it is not so") and "תמיה" (or some variant, meaning, roughly, "unbelievable") come up quite frequently, although this is often followed by "לפע״ד" ("in my humble opinion").

The terms "ולא היא" ("it is not so") and "תמיה" (or some variant, meaning, roughly, "unbelievable") come up quite frequently, although this is often followed by "לפע״ד" ("in my humble opinion").
