professional armchair pilot 

A professional armchair pilot is a person who is obsessed with aviation and aircraft, but has no actual pilot training or experience. They may spend hours studying flight manuals, watching aviation videos, and discussing the finer points of aircraft performance, yet they have never even set foot in the cockpit of an actual plane. Despite their lack of practical knowledge, these individuals may still consider themselves experts on all things aviation and may even offer their unsolicited opinions on piloting techniques and aircraft design.

"I asked John for his advice on flying my small aircraft, but it turns out he's just a professional armchair pilot who's never even been in a cockpit. I think I'll go with the advice of the actual pilot I know."

Archaius 

Archaius (Ar-kai-uhs) is usually a tall, funny, yet somewhat jokingly mean young man. Commonly having brown hair and hazel eyes. Archaius is usually mad that no one can pronounce his name right and likes to make chaos. He is usually considered the funny friend but wouldn't be categorized as popular. If you ever meet an Archaius, you will start off thinking he's annoying, but don't let this fool you, later on he will grow on you and you will forget ever hating him.

Person one: "Archaius drew on my paper today, he's so annoying"
Person two: "What do you mean? He's so funny, I wish I sat next to him like you"
Person one: "Yeah whatever."

I was having tea the other night with Chester while we were watching the flick My Mom blows like the wind. When the mother started blowing the daughter's boyfriend, Chester said "that dude is a bitch, he can't even get a hardon". He is such an armchair pornstar.
