A condition (one can have "lobbed balls" in the same way one can have a bad cold) in which the person has not had sex in a long time, but desires it.
Similar to "Blue balls", but usually more severe. Cannot be relieved by masturbation, only with actual sex.
Jim: What's wrong with Dean? He's being a total douche canoe!
Grant: Oh, don't mind him. His girlfriend's been out of town for the last few weeks, and he has a raging case of lobbed balls.
Jim: Oh, that sucks for him.
Randall: I can't believe my girlfriend broke up with me last month! Everything sucks! I just want her back!
Leo: Now, wait. Is that you talking, or the lobbed balls?
