Boohahas is a term used by guys who physically expectorate in trying to explain the attrativeness and specificity of how a female looks in a shockingly extonishing and exotic way to explain in male simplicity of how fine "she" may be at the time which they are trying to exemplify it. More specifically to a female chest area also know as breast.
