back on my bullshit 

def 1: "to be back on one's bullshit is to return to a state at which you were your truest and most vocal self with a renewed focus on authenticity and a decided lack of fucks given for others"

def 2: "it is the act or process of accepting your inevitable return to the self-defeating and impulsive behaviors that have historically hindered your self actualization but from which you cannot, and no longer desire to, escape."

Alright I had my time of sadness. Back on my bullshit let’s get it.
