Get the Shrimp Out mug.
When an angry white person takes their frustrations out on strangers because they have a small penis, low self esteem, a small mind/narrow world view, problems with the opposite sex of their own making, or some sort of trauma from their daddy not hugging them enough. These people are often young white males who drive Dodge Rams or similar vehicles but they can also be stuck up white women who get agitated that their Starbucks drinks aren't made to their exact specifications.
"Damn, that dude in the Dodge Ram Big Horn edition is really shrimping out by tailgating us so closely"

"What a pussy that dude is for shrimping out and shooting all those classmates just because that girl wouldn't give him the time of day"

"That bitch asked for a three pump, sugar free, non-fat white mocha and I only had two pumps left with no other bottles in the store. She really started shrimping out on me!"
