driggler

A person who is constantly fishing for answers from others and never actually contributes to solving problems. A driggler will often accost you just as you're in the middle of working and ask you to answer questions that you've answered many times before.

"Oh man... I was driggled so hard by this guy last night, that I couldn't get any studying done for my exam."

"Yeah.. that driggler just doesn't know when to stop!"

"That guy driggles everywhere!"
