Up"side` (?), n.
The upper side; the part that is uppermost.
To be upsides with, to be even with. [Prov. Eng. & Scot.] Sir W. Scott. T. Hughes. -- Upside down. [Perhaps a corruption of OE. up so down, literally, up as down.] With the upper part undermost; hence, in confusion; in complete disorder; topsy-turvy.
Shak.
These that have turned the world upside down are come hither also.
