Adjective describing guys who use shady
and sometimes creepy techniques to pick-up girls at bars. For example, inviting one girl to a giant "afterparty" at the guy's apartment upon the bar's closure, but not telling anyone else. Or stealing the girl's keys so she has to stop by the apartment to pick them up.
He invited me to an afterparty at his place, but then there was no one there but me and him. That's so lobo.
