A holiday taken out during a school week without the school knowing or having lied to the school.
E.g 1:

School person 1: Whaere were you yesterday? You missed your Maths GCSE exams!

School Person 2: I know, i was just going on a trucation.

E.g 2:

Teacher: Benjamin, back to school so soon?

Ben: Why shouldn't i be?

Teacher: Well, your mother did say your had a heart attack yesterday.

Ben: Ummm...It was just a really bad cough?

Friend: (whisper) You were taking a Trucation, weren't you?
