look up any word, like half chub:
When sitting near or next to someone and posting on their Facebook wall. This sometimes happens at cafes or in school computer labs, even among roommates. (comes from the word juxtapositioning)
I was creepin' on my roommate's page while he was next to me and I couldn't resist juxtaposting on his wall.
