A social alcoholic that convinces themselves that it is ok because others participate as well. Lushballs always roll in packs. Typically if one Lushball is going to have a cocktail there will be a domino effect and all Lushballs in the vicinity will need to imbibe. Always a good time, at least that's what the other Lushballs think. Blackouts are not uncommon and not frowned upon.
I really wanted to drink last Tuesday but I didn't have a wingman so I called my Lushballs. Then I blacked out.
