A situation where someone (often a woman) is unaware that they are engaged in sexual activity with someone else. Usually occurs as a result of unconsiousness caused by rohypnol, chloroform rags, sleeping gas, alcohol inebriation, and blunt force trauma.
John spiked Jane's drink with rohypnol and then took her to his apartment where he gave her stealth sex.
