A piece of used memory with no pointers to it. It's the equivalent of locking one of your drawers in your cabinet for then to flush the key down the toilet. The drawer is locked and hence you've got "one drawer less", but you can never access or modify what's inside it ...
When two person become strong friends of each other and none of them wants to go away from each other. Then they reserve some time and space for each other, which is protected by both of them.
To break their friendship you have to make one of the friends as weak friend, so that the relationship between them becomes weak from one side and can be broken.
Imagine the computer is a hotel, and programs are people coming to the hotel, and the rooms are memory. So, programs rent rooms (memory) and use them. Later, they can leave the room (memory) so that others can use the room (memory).
A memory leak happens when an person (program) leaves the room without telling anyone. Now, that room (memory) is locked there, and others cannot use it because the hotel thinks that someone else is using it. This is a memory leak.
Some OSs are smarter than others, and figures out that memory is not used and clears the memory and kicks out your program anyways. But some OSs like Windows, just keep asking 'do you want this memory anymore?'.
I'm a web sysop and support engineer. My skills are mainly in back-end: Java, Linux, Python, PostgreSQL, Git, and GitLab. Currently I'm learning front-end skills: JavaScript, and Ruby.
But "daddy not being able to walk around the house" is an externality. It's something caused by the 5 year old, but it is daddy who takes the cost. My 5 year old self would consider a house with floors covered in Lego the absolute ideal place to be.
I couldn't come up with an explanation for a 5 year old, but here's one for a baby:
You have 2 hands. If you want to pick up something you have to make sure one of your hands is empty. If you use up all your hands and forget to put something down, then you won't be able to grab things to put in your mouth.
Your computer has many many hands, but if you forget to empty the hands you'll eventually run out.

You're not five ;_;
A memory leak is like a five-year-old who won't clean up their room.
If you don't clean up your room, you will never find anything, and your room will also be to cluttered to dump anything more.

A memory leak is like eating food that you can't poop out. You keep eating it until you it fills you up completely and explode.
