Epistemology: Tossing is a euphemism for wanking, as you may call someone a "Tosser/Wanker" UK.
If you are tossing your salad, it means you are wanking furiously to season a salad with creamy mayo. The phrase is used in polite society as a euphemism to masturbation, and to denote that you are slightly peckish.
