Short for back to back.

1) Two DJs playing together. While one DJ is spinning a record, the other one is picking a new track. As they normally store their records behind them this usually makes the DJs face backwards on each other.

2) Business to business - there are two parties involved in financial or business transactions, traditionally sales of goods or services.
1) "The DJs at Intents Festival were amazing, especially Adaro b2b with Ran-D!"
2) "The local shop does business in b2b markets."

Business to Business. As in, the two parties involved in financial or business transactions, traditionally sales of goods or services.

contrast to: b2c, c2c
The Microsoft corporation does business in both b2b and b2c markets. Sun Micrososytems and Oracle (both floundering next to Microsoft) are primarily b2b focussed. While Ebay's business is mostly b2c (between Ebay the company and their users), the business they enable with their service is almost all c2c, between one user and another.

When an adolescent boy comes of age, Shrek flies into his bedroom in the middle of the night and shows him love up the anoos, long dick style. If the boy finds that he likes it... then hes gone B2B, or he's transitioned from Boy To Biatch
