You know a good grid when you groan at the answer! :)

don't get the drag clue

Drag resistance is what engineers try to do when they are designing cars and stuff, to make them go faster.
Drag race is two cars in a line seeing who is faster.
Drag n'drop is what you do with an icon on a computer, for example, when you move something to the trash.
Drag suit is something swimmers wear while training, usually a ripped old bathing suit, to make them work harder. A race in a tight suit seems easy by comparison! (I admit this is a bit of a stretch but it was designed for my swimming-crazy family)

Forgot their lead dingers dies-damn!Would`a gotta full house otherwise. It was good AliJ5.
