"デカくてトロくて." This is from a manga I'm reading, and here is the whole sentence "デカくてトロくて使いやすいジャンプ台だった." For context purposes, this is a soccer manga and refers to a part where a forward was sure to be the one jumping highest, only to be surpassed by a defender, who is the one saying the phrase. This defender use the other player shoulder to jump higher. I have no idea what デカ and トロ mean here. Any help would be really appreciated!!!!
