eagle head boner
a boner that looks like a skinny worm with a big, meaty head and a fat butt end, like it just ate a whole pizza.
Dude, my boner looks like a worm that just ate a whole pizza.
I tried to do a sit-up and my boner looked like a worm in a sausage casing.
My boner is so lanky and big-headed, it looks like it’s trying to escape a sausage link.
