Adjective: Texting shorthand for 'Single When She Wants To Be.' Said of a generally loyal woman who briefly violates her promise to her boyfriend (or husband) when a rare opportunity presents itself. A girl might be SWSW2B when her guy is OOT (out of town) and she strays for 1-night stand.
Justin's OOT till next week, so she's SWSW2B - sweet!
