If you are bossing the situation, you are running it. You are in control of what's going on. You do not follow, you lead the herd.

Get the boss mug.
A person who knows what he or she wants, knows how to get what he wants, and gets it when he wants. He or she lives by his or her own code and does not care about what others think. A boss has his or her own personality, and does not follow the norm, just because it is the norm. A boss does not settle for less than he or she is worthy of.
Gabe has his own ambitions to became a professional barrister. Everyone keeps talking about how hard it is to find a job, and how difficult it is to be in the profession, with juniors being unable to find sufficient cases. But Gabe still persists in becoming a professional barrister, as he is confident, knows what he wants, and could not care less what others think.

Gabe is such a boss.

Get the Boss mug.
A person who is of a higher life form than most feeble humans. They literally demand respect. All of their actions are aimed at consolidating their place as the top dog, and these actions are conducted in the smoothest manner possible.
Bosses often deny the fact that they are boss, but know in their hearts that they are. They are always winning.
The clothing of these men/women usually includes a classy, fitted Hugo Boss outfit.
Ari entered the room and everyone fell silent. They realised that they were in the presence of a true boss.
