Having everything to with being creepy, overly
touchy, unwelcome in advances or presence, may include, but is not limited to, those who are heavily intoxicated.
Probably derived from the use of
lurky and creepy combined, thus lur-py.
Many variations exist all with the same general implications. One can
lurp, be a lurp, a lurpster, a lurp show, be lurpy, be lurptastic, or do something lurpily.
"That guy was all over you on
the dance floor"
"Yeah he was really
lurping on me"
" Who is that guy staring at everyone from
the corner?"
"I dunno he's really lurpy"
