One possible synonym could be "friction," which refers to the act of rubbing against something, often causing heat or distress. Another option could be "abrasion," which is a similar concept, but typically involves more of a wearing away or erosion. "Conflict" is another potential synonym, as it can refer to a situation where there is tension or disagreement between two or more parties. Ultimately, the best synonym for friation will depend largely on context and intended meaning.
