A gay man's wife is called a beard. If they have a child together then the child is called a ZZ Top (in reference to the huge beards the band ZZ Top wore in the 80s). The child is in effect a "super beard" - used as an even larger cover up for the man's homosexuality.
Can't you see that Brian is a closet homo? His wife is just a beard and his son Pete is a ZZ Top.
One of many great bands/entertainers to come out of Texas. Ranked somewhere between Stevie Ray Vaughan and Pantera, but below Willie Nelson. More recent TX musical artists such as Bowling for Soup and Jessica Simpson can lick ZZ Top's bearded nuts.
ZZ Top's rowdy, shit-kicking guitar riffs revurbirate through your spine.
ZZ Top's "Sharp-dressed Man" is a great song to hear when you're getting ready to go out.
