What does ωπ mean in gain and phase margin calculations?

Hi, i was just wondering if someone would be able to tell me what ωπ means when finding the gain and phase margins on a bode plot?

In Bode plots, the horizontal axis can be in terms of frequency or of radians/second. The conversion factor between the two is 2π. So if ω is the frequency, ω*2π is radians/second.
