Slang: surf the Web

Definition: To look at Web sites sites on a computer.
Example: 1) I need to know some facts about Bolivia; maybe I'll surf the Web and see what I can find out.

2) Every night, my brother spends at least three hours surfing the Web.
Etymology: The 'Web' is the World Wide Web. As a verb, 'surf' means 'to ride a board on the waves of the ocean'. So this phrase suggests that the World Wide Web is like the ocean, and looking at different Web sites is like riding across the ocean's waves.
