eyebrows that are REALLY CLOSE to being a unibrow, but aren't quite there. they have to be really bushy, but not yet touching. you would have to be very attractive to pull these eyebrows off
"wow did you see joes eyebrows this morning?"
"no what happened to them?"
"they went all Greg Brady eyebrows on him, it's almost just one eyebrow!"
The Greg Brady is the opposite of Porky Pigging it. Where as Porky Pigging it is walking around with just your shirt on, the Greg Brady is walking around with just a bath towel around you.
Dude, I forgot to put my truck in the garage after I took a shower so "I'll have to do the Greg Brady" and put it away.
