When
one person is trying to describe a hypothetical scenario but another
person keeps contradicting their hypothetical scenario with another, opposite, scenario. Quite similar to Hypological Warfare
Guy 1: Let's say, hypothetically, I was holding a
shovel.
Guy 2: Let's say you weren't holding a
shovel.
Guy 1: But let's say I was.
Guy 2: But what if you weren't?
Guy 1: But let's just imagine that, hypothetically, I was.
Guy 2: But let's just imagine that, hypothetically, you weren't?
Guy 1:
Stop goin' all hypothetical warfare on me, douchebag!
Etc.
