I have a particular fondness for snort-laughs.
They are among the most graceless, horrid, undignified, embarrassing, beautiful truths in the world.

You didn't want to admit that the pun was amusing and give them the satisfaction.

You didn't want to break the societal norm decreeing silence and sobriety.

You tried to hide your innate childishness so condemned.

You needed to keep up whatever stoic, unfazed "cool" facade someone once suggested you wear.

You clenched your jaw against the giggle, but the spurt of it could not be contained and was released as a jovial exhale.
Graceless.
Horrid.
Undignified.
Embarrassing.
Beautiful.
