I have a friend who always speaks in a very matter-of-fact manner. On numerous occasions, he has mentioned how it was "the best BLANK" he has ever had, or "the best BLANK in the city."
Everything he speaks of is absolute in a overly self-assured manner (almost to a fault, since he is not always correct or has contradicted himself because of previous statements...how many bars in the city can have the best cocktail?). But on the other hand, he is very convincing/charismatic so it is easy to get swept away by his passion.
Anyway...are there any good idioms, or single words that might sum up this type of individual?
The following adjectives are the best ones I could come up with to describe this type of person: "very matter-of-fact" and "absolute" (but to a fault) but since he is so "self-assured", "charismatic" and "convincing" it's hard to see through this.
