P.C.S.R.P.
The time after a guy finishes having sex when he feels like a total piece of garbage for either A. Putting his cum on/in his partner, or B. Acting like a jerk after watching porn.
'I can't believe I just did that to her.', said no guy ever.
'I watched that whole movie and I still feel guilty.'
He turned his phone off after the third cumshot and yelled, 'I hate myself.'
