Slang term used to describe an older slang term of being "square" which was often used to indicate akwardness or someone who is completely odd. If you put the letter "L" and the number "7" close enough together, the two characters create a shape resembling a square.
I got lost in the city and ended up in an unfamiliar neighborhood where I felt completely like an L 7.
