look up any word, like blumpkin:
 
1.
Noun.
1. One who is never on time, never arrives promptly, and fails completely to give any sort of notice if he will not be arriving at all.
2. One whose very existence cannot be separated from that of his incessant tardiness and general flakiness.
Person 1: "Fuck, we've been waiting three hours for this guy to arrive. This guy's tardiness is tantamount to that of an Agui."
Person 2: "Seriously. If he keeps this up we should probably stop inviting him anywhere. You know, like we did with Agui."
