(something happens) whenever (someone does something)

Use "whenever" to talk about something that happens again and again in similar situations. For example:

He likes to stop by our office whenever he's in New York.

Individuals should be supported to make their own decisions whenever possible.

You could use "when" in each of these situations, but when you use "whenever" it sounds like it happens almost every time. If you use "when", it sounds like something might happen in that situation, or might not. So, for example:

I get a sharp pain in my shoulder when I raise my arm.

If you say this, the doctor might ask, "Does it hurt every time?" But if you used "whenever", the doctor would already know that it was every time.

(someone's) folks

"My folks" can mean your parents. This is a casual way to talk about your parents:

My folks moved here from China before I was born.

You can talk about other people's parents too:

How are your folks?

a bunch of (something)

"A bunch" means "a lot" or "many":

We have a bunch of leftovers. Why don't you take some home?

I lost a bunch of money on the stock market.

It's a casual expression and can sound kind of childlike.

(something)'ll (do something / be something)

The word "will" can be contracted to "'ll" after a noun like this:

My wife'll give you a call later.

The sun'll be setting soon.

No one'll find out!

This happens in casual spoken English. Avoid it when speaking or writing formally.

gorge (oneself)

To "gorge yourself" means to eat too much food. This word sounds a little negative, so you might say:

Don't gorge yourself.

We always use this word with "myself", "yourself", or other pronouns that include "self".
