I Second That. Edit Meaning

1.

a phrasal sentence that means, when taken literally, “I echo that statement of yours.”, “I echo your above statement.”; “I agree with you 100%ly.”; or simply “Ditto.”. See also "I second that emotion".

Phrase used frequently on message boards (more so than in person) by someone usually immediately after someone-else stated something with which the other person agreed.
