When two completely straight friends haven't had sex or anything with a girl in a long time, so they relieve each others tension by giving each other a blow job, but it is only considered gay if you don't say no homo.
JW: Hey man it has been a while since I have been with a girl, so do you think you can give me a bro blow? No homo.

GC: Ya man of course I got you I mean you are my best friend and all plus you did say no homo so it's not gay.

Completely normal action between two straight guy friends. As mentioned, saying “no homo”’ explicitly makes it not gay. One of the best things to do to show true bro friendship showing each bro you really care about them.
Dave: hey man I’m feeling down and could use some bro time.
John: I gotchu. How about a bro blow?
Dave: perfect!

Get the Bro blow mug.
A metaphor used when someone else blatantly contradicts themselves with a commonly used phrase.

The metaphor is of a person giving a blowjob to a bro, but it isn't gay since he said 'no homo'
Jake: fuck you! but no offense, though
Tom: yeah, a no homo bro blow
