Dear Teachers,

1. Do girls enjoy being hit on?

- What does "hit on" mean here?

2. If you worked out a little and bulked yourself up, that will make anyone look older.

- What does "bulk yourself up" mean?

3. The band Air Supply used to sing "Making love out of nothing at all".

- "making love out of nothing at all" means "making love for no reason", right?

Thanks a lot to Teachers,

Stevenukd.

I think that Air Supply was saying that they loved each other easily. It was easy to love.

(I hate song lyric questions. They are rarely grammatical and they often use abstract thoughts and use words in ways that are not common. Don't spend too much time trying to figure out what the mean.)

GG might well be right, but another possible interpretation of 3 is:
making love spontaneously
