To lay one's mack down:
1) To enter into an arena and get your
groove on.
2) To seduce a girl with your presence and your oozing charisma.
3) The physical act of taking off your coat or over garment and placing it
on the floor; being sure not to contravene any
health and safety regulations.
1) I bowled in, saw
the dance floor and simply proceeded to
lay the mack down.
2) That girl was all over me,
that's what happens when I lay the mack down.
3) I came in to the room, found an appropriate spot and thought this is where I shall lay the mack down.
