2.
n. The feeling of horniness coupled by a severe wave of depression. Related to Sexual Frustration, but with more loneliness and sadness. Often ends with drunken masturbation.
I just remembered this really hot sex I had with my ex. I really wanted to fuck somebody, but was simultaneously crushed by the feeling that I might never have sex again, and will never be close to anyone, and will die alone. Huuuuge deprection.
