Stands for Realistic Out Loud Laughter. Everyone is throwing around LOL so often now its lost its meaning. Its 2010. LOL is out. ROLL is when you actually audibly laugh out loud.
Rhymes with 'Troll'
This word is used within Gujarati Indian households, normally by a father, or male figure within the family. It is another word for washing machine, but used in the context of physically using a washing machine. It is not a direct translation of washing machine, i.e. you would not go out to buy a 'roll'. But to load the washing machine, you would be putting on a 'roll', therefore you put the 'roll' on.
'Has anyone got any clothes to wash, i'm putting a roll on'
'When the roll is done, can you put the clothes out to dry'
Son: 'Where's my work shirt?'
Dad: 'Check the clothes airer, I did a roll this morning'
