The first, usually very powerful, fart of the day.

Get the morning thunder mug.
I highly audible fart experienced first thing when one awakes. Often characterised by it's lack of flavour, dry texture and longevity. Often gives a great feeling of satisfaction.
Ahhh, I feel better for that morning thunder'

A loud eruption of gas released from the backside in the morning.
The calm silence of the bedroom was shattered from Daisy’s morning thunder.

Dude: *sleeping*

Daisy: *farts really loudly*

Dude: *wakes up* Daisy! That stinks!

Daisy: What? I had to get it out! It’s my Morning Thunder.

Dude: *holds nose* What did you eat?!

1) Inordinately great sex in the morning. As strong and powerful as a Bison.
2) A flavor of tea...to be had in the morning after having sex.
Man, I got two smashing cups of morning thunder today, Finneus.
