The orignal definition was touching, feeling, and assumedly handjobs. But now that society has become so desensitized to the intimacy of sexual intersourse, what with children giving birth at 11, 12, 13, left and right, third base has now been shunted up to second and the acts of fellatio, cunnilungus , and on occasion even anal sex, which have been traditionally associated with full-on sexual intercourse (i.e. making it home or scoring) have been placed on third base in order to enable today's alienated and cynical youth to give blowjobs and eat out pussy to their heart's content.
