A super goofy way to say laughing; usually said to a friend in a text when you know they’re gonna laugh at what you send, or when recalling a time when you were cracking up.
When a bear or a human pretending to be a bear laughs so hard they go into a hibernative state. (Tears are usually seen just before they enter this state) (It is also highly contagious and able to jump species)
Andrew's joke was so ridiculous that is caused Samantha to start laughing uncontrollably until she went into laughernation.
