Basically any person that is too in love and will do anything for their S/O. Including gay stuff like pegging and cross dressing. It is borderline slavery and those people are weak as fuck.
Somebody who does everything their girlfriend wants even gets off the gameimmediately when she says and to FaceTime. Mutes mic during game because on FaceTime, has a sticker on their car showing their significant other name. That is whipped.
