This is the definition of a base.
NO. A buffer donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic. So it donates H+ not OH-
it donates H+ ions
An Arrhenius acid donates H+ ions

You seem to be confused. acidic and basic are not things, they are properties. For example, vinegar is a solution, and it is acidic, because in solution, it dissolves to release hydrogen ions. Basic solutions, such as bleach, either accept hydronium ions in solution, or release hydroxide ions in solution. But all solutions, with the exception of distilled water, is either definatively acidic or basic. Look up a pH meter or a pH scale. The lower the number, the more acidic a solution is. The higher the number is, the more basic a solution is, and if it is 7.0, then it is neutral.
According to Bronsted-Lowry theory, anything that donates H+ (or protons) atoms to a solution is an ACID. Hence this defines an acid as a proton donor and a base as a proton acceptor.
A base can be defined as either a molecule that binds hydrogen ions or a molecule that donates electrons

-OH negative ions
Dissociation of a base produce hydroxyl ions.
