<human>: Can you succinctly summarize the text in 1-3 sentences?

For me it was this girl I was dating for a year and a half and then broke up with her because of the usual incompatible issues between two people. During some sexytime between us I ended up shall we say, "liberating in my pants". It wouldn't have been nearly as embarassing if I didn't have a shift to work shortly after and now was in need of a clean pair of underwear. She then bestowed upon me a silky pair of pink boxers and sent me off to work with a chuckle in her eyes. Naturally she teased me about it and we laughed about it for a good long time, but naturally once I broke our relationship off the hidden bitch mode I had never noticed before kicked in and jumped me. Walking around campus one day, she was walking with some of her friends and noticed me. She then proceeded to shout, "Hey, do you still have that pair of boxers I lent you when you jizzed in your pants at my place?" In front of a bunch of my peers naturally it totally took me off guard.
