1) preparing a salad. mixing greens.

2) slang. To humiliate someone by ordering them to commit the act of smearing jelly, or another desirable substance in your anus in order to lick it clean while you masturbate or they give you the reach-around.

Toss my salad came from an HBO speacial on prison. The seasoned convict was explaining what he would do to a new inmate in prison as sort of an initiation. He would get a packet of grape jelly and make the new inmate or "fish" smear the jelly in his asswhole and lick it out while he masturbated.
