megafaunal confidence 

The tendency of animals that are very large (megafauna) with few or no natural predators (such as adult grizzlies, elk, moose, etc.) to give off an aura of confidence and lack of concern for their surroundings in the presence of humans. These megafauna are majestic and either the top of the food chain and/or practically invincible and they seem to know it.

"Dude, that elk gives zero fucks that people are getting out of their cars and photographing it. It's practically posing!"

"It's that megafaunal confidence bro."

sucker confidence 

The confidence experienced when having a sucker in your mouth, esp. when talking to a crush. This phenomenon occurs due to the hands being occupied and just looking like a bad ass in general as you sensually draw attention to the mouth region. Also the fruity flavor helps to cover up creepy beer breath.

"How did Maggie work up the balls to go talk to that hottie Robbie at the terrace?"

"It was all that sucker confidence."
