What you refer to about the random, out-of-nowhere, BS that never has any reason that women come up with to:
A) Ruin a relationship
B) Randomly get angry at you
C) and subsequently pissing YOU off too
1) Guy 1: "Man I'm so pissed off"
Guy 2: "Why?"
Guy 1: "My on-and-off girlfriend randomly got angry at me when I looked at her, it doesn't make any sense."
Guy 2: "Buddy, WOMANITIS doesn't make any sense,"
Guy 1: "True that."
