After 18 days of
homoerotic exercise, a bear does 18 push-ups while a
twink either does/doesn't join in. This is commonly filmed and sent within a community of people. The twink usually masturbates to the activity, while
the bear sweats profusely and his bones crack in pain. (Some versions of the activity include the bear having an erection that has to touch the floor in each push-up.)
Upon completing the 18th push-up, the bear will moan "urgh, DAY 18" and the twink tries to ejaculate at the same time.
Person 1: "Ah
bruv, me and my
Bear are gonna do
day 18 today"
Person 2: "Ah my guy bruv, have fun g"
