Drag as in drag queen?

No relation, no. If something (or someone) is a drag, it’s boring or dull.

No. For someone to be “a drag” means that they are boring or unpleasant to be around. They drag your mood down. Similarly, a dull, tedious situation could be referred to as “a drag”. Compare the woods in Bob Dylan’s “Positively 4th Street”: I wish that, for just one time, You could stand inside my shoes And just for that one moment I could be you I wish that, for just one time, You could stand inside my shoes You’d know what a drag it is to see you In general, “a drag” is the opposite of “fun”

Also in English we don’t say ‘a drag’ for a drag queen. It’s not a singular noun. We can talk about ‘drag’ as the art form, or someone’s drag as their particular presentation of the art form, but an individual would be called a drag queen or drag king, or sometimes just a queen or a king in the right context.

If you can give the context it could help, but they're certainly using it as either boring or something that kills the fun "such a drag!" or if it's the greasers they're talking about drag racing, like they do in the LA river in the film. Drag racing is when you race a short distance in a straight line

No. Calling someone/something a “drag” is old-fashioned slang for “boring” or “dull.” The imagery is of a heavy weight that is *dragging you down* or weighing you down — so you are unable to have fun or move quickly, etc. It is not related or connected to drag queens.

No, it means that he's boring. Tedious, dull. Like if a movie drags on for too long, making you yawn.

You *heard the word “drag” “Listen” means to give particular attention to something making sound. While you were *listening to* the song “Summer Nights” from Grease, you *heard* that word.
