Thumber 

A sexual maneuver used to enhance the doggy style position whereby, without notice during vigorous pussy stoking action, the male licks his thumb and inserts it two knuckles deep into the girl's anus. May induce intense bucking and loud shrills which merely enhance the experience.

Rachel was bucking like a bronco last night when I surprised her with a thumber.
