LSLAB (pronounced 'L-SLAB') refers jokingly to a person on facebook who "Likes Statuses Like A Boss." This person usually just likes every status on his news feed and never often makes a constructive comment.
Nick: "Joe just liked every status on my news feed..."
Bill: "Joe's got some LSLAB action going on!"
