The act of taking something into your mouth by breathing inward or by creating a vacuum with your mouth for the consumption of liquid is to suck. This is similar to drinking, but the application of pressure is important. When a person or a thing sucks, materials or liquids go in.

  • You use a straw to suck on a milkshake.
  • Baby mammals suck on their mother’s mammary glands for milk.
  • A vacuum sucks up dirt and small objects around the house.
  • A hose can suck water out of a truck or a fire hydrant when there’s a fire.

The word "suck" is also very popular when describing something or a situation that isn’t good. But be careful! The use of the word "suck" is slightly vulgar. It’s not recommended in formal settings.

  • That movie really sucked. (It was a bad movie.)
  • Getting a flat tire on the highway during a thunderstorm totally sucked.
  • It must suck to have to work on the weekend.
