Jump hump is a type of sexual help where one person jumps on a bed where a couple is soaking (penis in vagina penetration with no movement.) The jump hump moves the bed for the couple, creating pleasurable friction like the friction couples having sex usually enjoy. Repeated jump humps, or jump humping, may make the couple feel good, but they usually stop before orgasm.
Jump humping originated in the Church of Latter Day Saints (LDS or Mormon) teen community as a way to enjoy sexual pleasure without technically breaking the religion’s rules forbidding sex outside marriage. While couples who soak enjoy sexual pleasure through jump humping, they believe they are not technically breaking the rules as they are not moving their own bodies. By this logic, they have not committed a sin in the eyes of God. The term jump hump has been listed on Urban Dictionary since 2011, but went mainstream in 2021 as teens discussed and filmed the trend on the social media video platform, TikTok. The term hump jump is a common variation of jump hump.
