While glancing at Twibooru, I came across an MLP:TNG image I couldn't properly interpret. What, precisely, does "ゴゴゴ" mean?

Aaaand, I see that's a tag. Which is semi-translated as "go go go" though I don't know if that's like in Xcom-Chimera, where the team shouts "Breach! Breach! Breach!" except when the character instead says go, go, go. Or is this like "Go now! Go take a long walk on a short pier! Go! and play hide and seek by yourself!"

Further instances have not exactly clarified like butter in a cooking class.
