A squirt is a small amount of liquid that comes out quickly and suddenly.
You probably know what I mean when someone says "Oh no, I've got a squirt of water on my shirt!" It usually happens when you're getting dressed or doing something with water. The word can also be used to describe the act of spraying a small amount of liquid - for example, squirting yourself with sunscreen before going out into the sun. Sometimes people use it in a more playful way too, like saying "I just got squirted by a kid's water gun!" It's a fun and informal word that's easy to understand, even if you're not from an English-speaking country.
An instrument from which a liquid is forcefully ejected in a small, quick stream.
(of a liquid) To be thrown out, or ejected, in a rapid stream, from a narrow orifice.
Example: The toothpaste squirted from the tube.
