Bonking 

In endurance sports, particularly cycling and running, hitting the wall or the bonk describes a condition caused by the depletion of glycogen stores in the liver and muscles, which manifests itself by precipitous fatigue and loss of energy. Milder instances can be remedied by brief rest and the ingestion of food or drinks containing carbohydrates. The condition can usually be avoided by ensuring that glycogen levels are high when the exercise begins, maintaining glycogen levels during exercise by eating or drinking carbohydrate-rich substances, or by reducing exercise intensity.

I bonked at 80 miles, just nothing left in the legs.

I completed the marathon without bonking.

Boxing Gloved 

The extremely full, and often painful, feeling as if a boxing glove is being shoved up your rectum during an anal fisting. Most often occurs when the individual receiving has an exceptionally tight and tiny rectal cavity and their fisting partner has extremely oversized, large hands. Feeling may also be achieved by someone sporting Sausage Fingers.

Tonya was excited to try fisting for the first time. Her tight little virgin bung was arched up in an organic spread and thoroughly lubed. However, she was forced to stop after feeling like she was getting Boxing Gloved by her boyfriends thick, girthy Sausage Fingers.
