This is what prostitutes use in ads. It means they’ll do everything but actually have sex. They’ll suck your dick but won’t let you finish.
'Half sex, full price. What’s the difference?', a hooker's ad
'She gave me a blow job but ran out before I could get my pants off.', a guy's text to his friend
'I paid for half sex and got a face full of lipstick.', a dude on Twitter
