Hi Lena. Gasp is a sound of surprise. Snapped has many meanings. If you snap your fingers it makes a sound. Branches from a tree can snap under your foot. It is a sharp sound. Chirruped is a sound from a bird. When a person chirrups, it means that they talk in a high pitched voice. When you raise your eyebrows, your forehead crinkles. If you make paper into a ball it crinkles the paper. Approached means came near to. When you can see that you are going to fall, you brace yourself. It means to stiffen your muscles. Also tonger is not a word. I think it should say tongue. Rolled off her tongue means that she said it easily.

'Bollocking' is quite a crude term as 'bollocks' is a slang term for testicles. 'Bollocks can also mean nonsense/rubbish depending on the context i.e if someone is talking bollocks then they are talking nonsense.
However, now we come to 'bollocking.' It's an informal term which essentially amounts to a 'telling off' or perhaps more accurately a 'dressing-down' or a 'reprimand.' It means to speak to someone angrily because they have done something wrong. Like I said, it is very informal and quite crude.

The line she'd been daring herself to say rolled off her tongue

"I dare you to ..." is a challenge - from "I dare you to say where you were last night" to "I dare you to do a parachute jump". I could dare myself to say something in Russian!

I'll give you 2 examples:

"I love you" is a line that indicates that a friendship is getting serious, so she might have been waiting for the right time or situation after thinking about it for a while. "daring herself to say" is similar to "plucking up the courage", "rolled off the tongue" typically means that is was said without hesitation or possibly unintentionally - thinking out loud.

In a work situation, like an office, there could be a person who cannot stop talking (a "chatterbox") and keeps interrupting. You want to tell them to "shut up", or "go away". You might resist until you've had enough.

Does that help, Lena?

Bollocking means angry words said to someone who did something wrong. Scolding is another word that means the same thing.

Also, this is a singular word, these is plural. So it is either this phrase or these phrases.

Good question.
