dehydrated walrus

A subspecies of women that weighs at least 200 lbs, and can't seem to drink enough alcohol as if she were dehydrated. She is also loud, obnoxious, and a complete cock block. She will purposely sabotage you from hooking up with any of her friends and insist you buy her more drinks because nobody will fuck a dehydrated walrus.

"I will never get a shot with Mary. Her friend, the dehydrated walrus, is killing my bank."
Bar tender - "Sorry sir we have no Shmirnoff, Bud Lights, or Twisted Teas. That pack of dehydrated walruses have damn near drank this bar dry!"
