Calmquit 

1. Similar to a ragequit, when someone quits an online match in a fighting game or first-person shooter out of fury of losing, with the primary difference being in having a relatively relaxed disposition upon quitting. Calmquitting can be caused by things other than a lack of skill, such as a busy schedule or simple apathy.
2. A ragequit where the ragequitter was not audibly or visually angered to the point where you wonder if the online connection was simply disconnected.

I could've won, but I realized I was gonna be late to work, so I had to calmquit.
