a combination of the word MAC and jacket. Associated with the junior rowing team Marina Aquatic Center in Marina del Rey,CA whose uniform consists of wearing a sick red jacket with the letters mac written across.
random rower:why didn't you wear your macket today it's freezing?!
MAC rower: Do you even row for MAC?.....
MAC novice: I haven't gotten my macket yet, all i have is this mac sweatshirt with a retarded hood fml :'(
Portmanteau of the words Meat and bracket.
This is when two males press their erect penises against the left and right side of a female's face, thus producing the meat bracket.
If a third individual takes the front of the female's face. This is called "The Three Macketeers"
Yo, Mason, let's macket this snitch's face.
