I've been trying to find a word or brief phrase that describes a person who constantly emphasises, or compares, the size of things, superlatives.
E.g. I watched a TV programme recently, the host was describing a production line, and he was constantly (and irritatingly) pointing out the figures about how "good" the machine is - things such as line speed, units produced per hour etc - emphasising the quantitative facts rather than the qualitative information.
Does anyone have any suggestions as to a suitable word or short phrase that might be appropriate in this case?
