In Spanish slang, 'pescar' literally means 'to fish', but it is often used to mean 'to understand' or 'to get something'. It can also mean 'to ignore' or 'not pay attention' depending on the context.
Examples
- Spanish: No pesqué nada de lo que dijo el profesor en la clase de hoy.
- English: I didn't catch anything the teacher said in today's class.
