A socially unacceptable act usually ending in several others acting strangly towards the perpetrator.
Something a person does in total disreguard to social norms.
When a relationship has been over for half a year and a girl drives 10 hours to stay with her ex's parents while he is away, "accidentally" forgetting he is supposed to come back during your stay. Upon returning, the ex is alarmed and makes an attempt to ignore/avoid the girl, which causes her to not understand, become angry, and continue her stalking. The girl finally gets the hint and embarks on her 10 hour journey home just to complain and act suprised about the ex not graciously accepting her creepy stalk mission.
