Grease Slicker
When you take someone’s hair and squeeze the grease into your mouth to clean it.
After me and my gym bud got home from the gym I noticed how greasy his hair was. I asked him if I could give him a grease slicker and he said sure. So I grabbed a big chunk of his hair and squeezed the grease into my mouth and swallowed it. He thanked me for my kind deed.
