I used Manic Panic Electric Lizard Green as we went clubbing and it glows under the uv lights.
Let me tell you honey, great idea at night time when you're in high spirits with a group of like minded and similarly dressed friends but terrible idea when you have to face the suits on the underground looking a reject hooker from Michael Jacksons Thriller video, embarrassed wasn't the word!
What's funnier is that one of my friends somehow managed a photo of me looking like that with my head in the toilet, i promised her i'd scratch her eyes out if that ever became public. Awkward!
