Forks over is a slang term that refers to giving or surrendering something, often unwillingly. The antonyms for this phrase include withholding, keeping, retaining, and hoarding. If someone doesn't want to fork over their money or possessions, they can choose to withhold them instead. Retaining means to keep possession of something without giving it away or relinquishing it. Hoarding refers to keeping a large amount of something for oneself, typically in excess of what is needed. In contrast to forking over, these words all suggest a desire to hold onto something rather than give it up.
