When 2 cars in different lanes both switch into their counterpart's lane at the same time.
eg: Car A moves from the left lane into the right lane. At precisely the same time Car B moves from the right lane into the left lane.
Commonly the cars involved in the lane exchange are in close proximity (1-3 cars apart) however an exchange can take place over greater distance without either party being aware of it.

To engage in an intense 69 session with a fellow male for (hopefully) long periods of time followed by swallowing each others loads.
"Dude, you up for another brotein exchange? I'm horny as fuck and my balls are full." "Same here bro. Horny as fuck too. I know you love the taste of my sperm. My parents aren't home so we can get together here."

A potentially sticky situation where both you and your best bud are close and your mutual friends think you're both str8 because you have girlfriends, but you're actually surreptitiously meeting for gay/bi sex aka a brotein exchange. These hook-ups include alot of sucking each other off and swallowing each other's loads in addition to mutual foot worship.
When the girls thought we were spending the weekend at the shore, we were actually engaging in a brotein exchange at a motel down by the airport.
