the farting triangle

so me and my partner were rolling today in class. he's trying to pass my open guard,so right in the middle of this exchange,i inadvertently blow ass wind,so he started laughing his ass off,i say i'm sorry and we start again,the fart itself must've threw him off because i triangled him shortly after hence "The Farting Triangle"

how did he try to defend?

pull his gi over his nose?

turn his head?

bury his face in your chest hair?
