short for South Boston aka southie MA, a hood in boston. No one in boston and southie calls it sobo.
This is a term coined by realtors to make southie sound trendy like the back by or
south end. This term is harshly rejected by long time southie
residents who know its a gimmick to lure in rich yuppie bastards.
Yuppie- "I'm moving to Sobo where I will buy a condo for $500,000so
I will be closer to my cube downtown"
Southie Guy- "Are ya Fackin
retaded its called southie, not sobo you yuppie bastard,move back to
vermont"
