A group or random collection of past events that a dumbass female will use against a man while engaged in an arguement to attempt to make said man feel as shitty as humanly possible. Even though majority of these said events at the present time are outdated and no longer apply to the current conversation.
My wife flipped through her Mental Rolodex to give me shit during an arguement by telling me that I should have married my Ex-girlfriend knowing damn well that cunt cheated on me.
Something you "store" memories in when a friend has said something stupid or pointless.
That's great; I'll put that in my mental rolodex so I can blog about it later
