def 1. a feeling in the inner circle of a virtual or actual social group that someone outside that group needs to move on, especially in an internet forum.

ety. A sepling of 'weird'.

ex 1. "That alt is making me feel werid."
ex 2. "I get a werid vibe from that post."
ex 3. "Are you getting that werid feeling again?"

Note also the similarity to 'derision'. A possibly derisive remark...although not necessarily so as one can get that werid feeling without malice.
