One or more people that show up at your house to do a job and have a car full of tools and tools in the trunk and they don't do the job well and you have to pay someone else to do it
1. Those trunk slammers,( see above definition), really did a job alright after them I had to pay double to fix what they broke and then the real job. 2. I told you not to hire trunk slammers for this job you fired.
Trunkslammer- someone who does a type of construction out of his vehicle and does not seem professional . Someone with little knowledge or experience that is not good at what they are hired to do
Those stupid trunkslammers just destroyed my bathroom, who puts 17 x 17 inch tile on a ceiling?!
