I disagree, f5 is much worse than b5.
The f5 Opening

falcogrine, the person posted when I was at 1200, he said go to 1400. I'm at 1400, so f5 works in blitz!

This is a joke. f5?? g6??? How can you possibly justify losing 2 pawns and exposing your king for no compensation? You can't, which is why not one person who has posted here thinks your garbage opening is anything more than a forced win for white. Thanks for trolling, goodbye!

No, we said 2400, you said 1400.

No compensation? Seriously?

e4 e5 knf3 f5 is a good way for black to try and seize the initiative early doors maybe your line just needs this little tweak to make it a good weapon
Thought this was going to be about 1...f5 against everything but 1.e4.
Against 1.e4 we can call 1...f5 the suicidal retard pawn.
