Tribadism
Tribadism /'trɪbədɪzəm/ (Greek: τριβειν, to rub, + -ισμος, condition, ism] is a sexual practice where two women rub their external genitalia against one another for clitoral stimulation. An alternative name for this practice, including other sexual rubbing, is frottage.
The word is derived from the obsolete word tribade, meaning "lesbian", and until the middle of the 20th century (sometime before 1965) meant "lesbianism". Also known in slang as "donut bumping", "monkey bumpin'", "bumping uglies", "slapping clams" or "scissoring".
