SB = any sort of boner. Specifically a Spontaneous boner. This slang is created, to be able to talk about any sort of boners in front of a girl, without them knowing the definition.
a hot girl passes by...."ohh dude, SB!"
or, if u get a boner in class, u would like to share with friends...."man, i just got an SB!"
