Smiling Quietly To Myself .
More accurate then saying LOL when your not really laughing out loud.
When i receivced the sweet text my boyfriend sent me i responded sqtm :).
When my bff texted me the most hilarious text during history i was sqtm.
An abbreviation for "snicker quietly to myself." Meant to be a more-accurate replacement for "lol."
"That's what she said! sqtm"
