A KFC sandwich which features two boneless white meat chicken filets (Original Recipe® or Grilled), two pieces of bacon, two melted slices of Monterey Jack and pepper jack cheese and Colonel's Sauce. The sandwich was originally advertised as only having 540 calories but later analysis by 3rd parties placed the calorie count closer to 1190 calories.

After a hard session of pumping iron, you come home and ejaculate into a cup. You then combine protein powder with the semen in the cup to create an extra potent protein shake. This process has the added benefits of raising ones testosterone levels (by climaxing), and making you feel as though you are saving the world through recycling.
"After doing chest and tri today I only had one scoop of 24g protein powder, so I decided to double down to boost my recovery."

"Dude... that's really gay..."

"Nah bro, these dancing pecs get me so much pussy at the bar."

The "Double-Down" is a famous rap song made known by the notorious BIG D. BIG D makes his presence known in the streets of Chicago beat boxing where anyone who is important walks. When it is your first time hearing the magic of the "Double-Down", BIG D is gonna bring it to ya nice and slow...no one knows why.
The "Double-Down" has no lyrics just "da da da da Double-Down". But surprisingly, when song with different pitches, tones and beats at certain times, the "Double-Down" is very entertaining.
In the future BIG D is gonna make a tight dance to go along with the "Double-Down" and bust some more verses for his song.
The "Double-Down" is a must hear whenever you are in Chi-Town.
Yo have you guys ever heard of the "Double-Down"?

A sexual position inspired by the KFC sandwich which features two boneless white meat chicken filets, two pieces of bacon, two melted slices of Monterey Jack and pepper jack cheese and Colonel's Sauce. As the guy is having sex with a girl doggie style, he flips her over and cums his Colonel's sauce on her stomach, slaps 2 pieces of bacon on her then grabs the other girl he just finished having sex with and throws her on top of the girl he just came and slapped bacon on and VOILA you have the Double Down. 2 boneless breast, bacon and cheesey/colonel sauce in the middle.
As Jim drove through the KFC drive through to order the famous Double Down sandwich, he fantasized about doing The Double Down with the hot twins he met from last night's party.
