Thumb Method

When you jerk off over your pants using just your thumb. This is commonly used by those who have an inability to release sperm.

When I was sleeping with my parents in third grade, I used the thumb method so I could get off without them knowing.

Thumbing my nuts

An expression of awkwardness. When you find yourself suddenly alone, bored and with nothing to do. Can also be used to convey a feeling of abandonment.

“Where the hell have you guys been? I’ve been sitting here all night thumbing my nuts waiting for you!”
“Well I’m not gonna just sit here thumbing my nuts!”

Throwing Thumbs

To like posts, pics, shares,...etc in an excessive manner. A person who spends way too much time on Facebook liking everything, to the point of ridiculousness.

Everytime I turn around, Donna is throwing thumbs on Facebook. She needs to chill out.
