Sometimes people, when talking, inadvertantly make a pun (play on words) which might appear humorous in a serious situation, or flippant. If this happens, they might say "excuse [or pardon] the pun" or "no pun intended". Sometimes people say "pardon the pun" to bring attention to the fact that they have just made a pun and want the listener to know that they have punned, in case they're stupid or inattentive.
A surplice is a diagonally crossed neckline or bodice.As such it is a thing which does not have an "antonym" (opposite).Perhaps a miniskirt? or a thong? or a nihab? or a pair of shoes? or an elephant? or a super nova? or a dream?

The dictionary doesn't give any but I might suggest some closely related that might work, such as straightforward or humorless.
