Jacksmart
When a guy thinks he's the most clever person ever, just because he said one word at the right time. It’s when he drops a comment so good, it makes your brain short-circuit.
Jack says, 'I saw that coming a mile off,' after you fall into a puddle.
He calls a loud argument 'a verbal battle,' and no one understands what he's talking about.
He says, 'I had this planned for ages,' after you miss his train.
