SMBS:verb: Suck my ball sack. Its a form nicer thzn saying FUCK YOU!, Or saying the literal "suck my ball sack". SMBS (sounds like SMIBS) is a lot "nicer" but still gets the point across.
It means save my back soul.
This is a word used when you're in a situation when everyones happier then you and you feel like you're the odd one out.
This isn't a bad thing its a observation that you have made
SMBS means:Save My Black Soul Can someone please save my black soul i'm the least happiest one here. Everyone is really happy but me, I'm not sad (you could be sad) but I'm not as happy as them.
GIRL ONE: I LOVE THIS SUNNY WEATHER
