A utilitarian typo of marbles used to denote having giant balls of awesomeness. Also anything that has to do with balls (of any kind), memory, and spherical foods.
-DUDE! That guy just punched a beehive!
-Woah! He has some serious marballs!
used to describe a situation that is undesirable for whatever particular reason(s). Derived from the word nightmare which has been joined with the word balls to create "mareballs"
"OMG! I was out last night and I fell over a table of drinks in front of everyone- complete mareballs!"
