look up any word, like donkey punch:

After sensual foreplay, the woman gets on her knees (like she's supposed to) and prepares to give the man oral sex. Before the throat is swabbed, the female packs an extremely large lip (chewing tobacco). This combination provides for ecstasy and a nice head buzz.
Sherdaddy: Why are there all these empty waterbottles on your bed?

Full definition:

Most commonly known as an astronomical configuration of stars, the big
dipper shares a same level of amazement as well as shear power. Extensive testing and experimentation began early in 2008 by two amateur visionaries native to the San Diego region. With hopes to bring change to a seemingly poor state of sexual culture, these two patriarchs have become fondly known as "The Fathers of Fulfillment."

One might refer to this tantalizing activity as the more attractive older brother to the all too familiar "Tea Bag." Much like Tea Bagging--this activity is not for the faint of heart, nor the orally disadvantaged. The recipient in hopes to be "dipped" will lie on his or her back, with mouth agape. The bearer will then position himself above the other, sure to have removed all lower garments, and will slowly begin to lower himself being mindful to align his penis and testicles to the target mouth.

Now keep in mind, the man must remain calm, so as not disrupt the delivery. Things could get "messy" if one looses his flaccidity. And as for the recipient, a little help is not frowned upon, a simple guiding hand will surely relieve some of the pressure off of the already anxious performer.

Okay, now lets get down to business; the completion. Once you are properly aligned, it is now safe to initiate drop sequence. It is completely up to the dipper how much force is used when entering the said mouth. Assuming there has been verbal agreement, so as not to surprise the recipient and therefore prevent possible clamping.
Now place the entirety of your genitalia into the mouth, get comfortable, and enjoy "THE BIG DIPPER."

Short Definition:

When a man dips his dick and balls into his partner's mouth.
"Hey Rafael,
did you get a BJ last night!?"
"No man, better!
I got The Big Dipper!!!"
