when a male is having intercourse, their counter partner screams Russian Jump as the male ejaculates thrusting her body towards the male increasing the penetration. This may lead to the damage of male balls, however it is very effective.
"My girl tried the Russian Jump on me and now I don't think I can feel my balls anymore"
"that sucks bro, I pulled out before mine said that"
