Actually chuckling out loud. Since the phrase "LOL" has lost its meaning, there is a need for an acronym that actually means that one has literally laughed out loud in real life. However, since it is rare to flat out laugh out loud because of reading something that someone has typed, it is more realistic and accurate to say that one has "actually chuckled out loud."

Misinterpretation held by many people's moms - "lots of love" instead of "laughing out loud." Best to use it in a situation where "lots of love" would be very empathetic and appropriate, and "laughing out loud" would be incorrect, disrespectful, and downright horrific.
