I laugh like this:
1) Someone says something / I see something / Someone does something funny.
2) It triggers in my brain as being humorous.
3) My lips upturn to a smile.
4) My mouth opens.
5) My stomach contracts.
6) I let out a sound - one that sounds like this: "Ha! Ha! Ha!"
7) Depending on HOW funny the thing was, I carry on laughing in this manner, or I stop.
8) If I have been laughing for a long time, my stomach hurts.
...And that's what you call sarcasm.
