The Yackley 

A vertical anal position term used for when you’re doing it in the ass while holding a handstand and your mate is standing behind penetrating the asshole downwards. The Yackley works best when one has good balance (yoga helps) and can hold the headstand position long enough for the male to finish.

“Let’s do anal” “Yes, but lets do it The Yackley way”

yacking the alphabet off 

To talk incessantly! Blow one’s phone up.

Look at that poor guy over at the bar, that girl is yacking the alphabet off. Yeh he can’t get a word in.

I am so sorry I was yacking the alphabet off yesterday. I will refrain from blowing your phone up
