Is a way of using the tip of balalaika as a dildo. Mostly done by russian men(can also be women). Most common way is to put in balalaika up in ass while singing kalinka. It is a fun way to cheer up people in a party with people from CIS countries.
-Last night I saw a russian man doing ''Balalaika Dildo'' at a party. He was not even drunk. He looked happy.
