In Russian we have a verb "Намыль", which means take soap (assuming either wet soap or dry soap depending on context) and rub it to have it cover something. What is the equivalent in English?
I thought the word "soap" as a verb would help me out but unfortunately it means "wash with soap" while I needn't include washing.
I can't find the right word or phrase to use in English.
Edit: We mostly use it when we distinguish two actions. When, for example, a person is in a bath tub and asks somebody to cover his body (back or head for instance) in soap he would say this verb.

, the answer you accepted. I'm not suggesting you resort to GT for these cases, I just find it interesting.
