I will now recall a recent conversation with a friend (I'll call him "Jim." Names have been changed to protect the innocent).

Jim: *trying to think of a name* What's the name of the girl I pissed off recently?
Me: Jenny?
Jim: No, the other one.
Me: Cindy.
Jim: No, different one.
Me: Ann.
Jim: Yeah, that one.

He pissed off Ann by skipping her birthday party and going hiking with Cindy. He pissed off Cindy by admitting he liked Jenny's roommate, Alyssa. Jenny, of course, liked Jim, and was pissed off that Jim liked Alyssa.

Jim's pretty good with the ladies.
