where LOL stands for Laugh Out Loud
and ROFL stands for Roll On Floor Laughing

introducing SOF:
SOF stands for Smile On Face

people use LOL and ROFL even though they may not actually be laughing or rolling on the floor. instead we sit there with a smile on our face because it was a humorous comment but not enough to induce laughter.
(on an IM or BBM or SMS convo)

dave: yo man i heard a great one today

mord: go for it bro

Dave: why did the chicken cross the road?

mord: why?

Dave: to get to the other side

mord: SOF

Dave: what, only an SOF, i LOL'd so hard

mord: sorry bro, it was only SOFworthy

Smile on face. Rarely does one "laugh out loud." They usually just have a smile on their face.

That sounds like a solid Christian ministry, but I need to read their SoF before deciding.

soffing, stands for playing the game 'soldier of fortune'

it can also stand for hitting somebody in the gutand when they are bent over you kick them again but this time in the groin:)
1) me and some buddies went soffing online again, man we beat those foes so hard.

2) yesterday me and a guy got in a fight, he soffed me like three times, then I passed out.
