Explanation of Emoticon Requested, Please

[rebecca430]

Hello!
I have not held an account with FusionCash for very long, and therefore I need some things explained to me from time to time.  I hope this does not prove to be bothersome to the more experienced members of the site, as they were once new here as well. 
I like all of the cute little emoticons we can use, but I do not know what this one means:   
What does this flag in the emoticon mean?  I have never seen such a flag as this before, and I cannot figure out for what the "BS" stands.
Any assistance in explanation would be greatly appreciated.
Thank you for your time,
Rebecca

i believe it means "bull sh*t". since there's 13 year olds on here, we kind of have to take it easy with the language.
