"Bump" your topics simply by clicking a "Bump"-button

sorry for my ''bad'' knowledge of English but what is BUMP means in this sentence ?

Bumping is forum-language for posting an extra post so your topic goes to the top of the "new posts"-list. Some forums have a function where you go to your topic and click a button called "Bump" that does the same thing, only you don't have to make a new post for it to happen.

You often see people trying to sell a watch and not get any response in 24 hours posting a new post in his/her topic saying only 'Bump'. The BUMP-button does away with these one-word posts.
