The type of person who is always asking for advice, yet never takes it, preferring to fart around and waste everybody's time, often doing the totally contrary thing to the advice given.
Jeremy is such an askhole - he came for advice on this and ignored my years of experience; as a result, he lost a packet.
That guy you know at family gatherings or work who asks your advice or help for something they basically suck at. Without exception, askholes reward you by arguing about your advice to seem an equal.
Also universally, askholes reject your advice, fail publicly, then shift part or all of the blame to you. Because they did the opposite of what you told them. After they asked you.
Askholes are incredibly greedy with your time, ut generous with their own. They'll spend hours giving newer employees and new family members advice you must then advise them to forget.
