Holding up your muscles in a strong-man pose; showing your support for Zach Lederer and his fight against brain cancer.

Synonymous with "Keeleying"

"Lederer said that with each post in which someone is 'Zaching,' he or she is also supporting 'every cancer patient you come into contact with.'”
"Tebow-ing? Nah. We're Zach-ing."

"University of Maryland Alum and Baltimore Ravens WR Torrey Smith is Zaching!!!"

"DANE COOK ZACHING EVERYONE!"

"This is not a random picture of the Naked Cowboy flexing found online! He is actually Zaching for Zach!!!"
