"Glueballing" refers to the practice of applying hair gel to the penis and pubic hair prior to intercourse. The result is that both parties become "stuck" to each other at the point of genital contact. Those who engage in this practice either find the act of getting "stuck" directly pleasurable, or they indirectly take sexual pleasure from the painful sensation of genital adhesion.
