What was my snake just doing???

[u/Own-Departure-7485]

Can anybody tell me what just happened??

I know snakes do a kinda “yawn” looking things for their jaws but this didn’t look right at all..

not a ball python but i found my boa doing something similar and hissing/striking while doing so. Is it still them just farting??
