big kacper energy 

it's pretty much the big sad. you are just so incredibly sad but you can't figure out why, there is no real reason for this feeling, you almost feel sentimental about the past, there is a hole in your heart that you cannot fill.

However, Big Kacper Energy can be easily avoided if you take your mind off of it by listening to your favorite music or doing something productive. Big Kacper Energy comes and goes so don't worry about it too much.

Person 1: yo dude I'm having big Kacper energy today :(
Person 2: Dude just listen to some music, it's all going to be fine :)
