When you are so drunk you can't feel a thing. After an evening of drinking plenty of beer, you fall or hurt yourself and rebound as if unscathed; you had on your PBRmor.
"When biking back from the bars last night I ate serious shit. But no worries , I had my PBRmor on- I jumped back on and hauled ass the rest of the way. Still woke up with the bruises & hangover though."
"At least she had her PBRmor on, she would've started balling
after that fall down the stairs if she was sober."
