A term used to describe a closeted (gay or otherwise) individual who does not do the best job at hiding it. It sticks out as a sore thumb, or rather, as a piece of tape on somebody's leg.
"Ugh, you see him over there? That guy is such a tapeleg."
A tape person is like double-faced tape: a bit of a hypocrite with two opposite faces to their personality which makes them irritating and sometimes unbearable.
She told you she didn't like her and praised her at dinner last night. She's such a tape person.
