An acronym standing for "Suns out guns out". Suns out guns out is a special time of day when the sun peaks out from behind the clouds. At this exact moment it is necessary to rip your shit off, yell "SOGO!" and show off your guns. The combination of these actions will kill every living organism in one-mile radius and you will most likely be slammin some v within the next 5 minutes.
I was hanging out with Sarah earlier today and had a SOGO moment. That's why she fucked me in the McDonald's parking lot.
