What does all hetero mean?

all hetero meaning in Urban Dictionary

The expression "all hetero" is synonymous with samples of the literary devices of modifiers. The term strictly clarifies & categorizes a statement as heterosexual (perhaps not gay), that possibly might have been viewed as heterosexual or homosexual. This might be differentiated from no homo or no bruno, because both of these phrases are accustomed to simplify the heterosexual intent of an otherwise homosexual statement. But the expression "all hetero" may be used in a "no homo declaration," but not the other way around (as a "all hetero statement" might not have already been homosexual in the first place).
