You miscreants (and you know who you are) are using a word to mean its opposite, and you're doing it without irony. If you hear a word for the first time, you have a responsibility to determine its correct meaning before you pass it along. Do not let the destruction of English be your fault.
For the record, here's a definition of the adjective:
filled with bewilderment; "at a loss to understand those remarks"; "puzzled that she left without saying goodbye" [syn: at a loss]
And here are definitions of the verb and noun forms:
verb, -plussed or -plused, -plus·sing or -plus·ing, noun
–verb (used with object) 1. to render utterly perplexed; puzzle completely.
–noun 2. a state of utter perplexity.
Thank you for your kind attention to this matter. We will return shortly with more dirty pictures and poorly edited ramblings.
