EXCLUSIVENick Swisher's reputation as one of the best partiers in baseball just hit Van Wilder levels, cause while the rest of the league is tossing around weights to get big ... HE TOSSES KEGS.

Check out the clip -- It's pretty awesome to see Nick training in the snow a la Stallone in "Rocky IV" (greatest training montage of all time).
FYI -- Rocky defeated Drago and won over a country ... Nick is batting .207.
