shagger's nod

A nod of recognition between two shaggers. Much like the common "runner's nod", it is a simple nod of encouragement to a fellow shagger, tacitly telling them to "keep up the good work!".

"So Declan now had a girlfriend, and Shagger's Nod began to replace 'hello' as we passed each other in the library. Finally, he was part of the club."
