I would do my part
A fancy way of saying you’d be the first one to grab the hot girl if she was standing in front of you, no questions asked.
I would do my part if she walked in and I had no pants on.
I would do my part if she asked me to help her move and I said 'Sure, but I need a drink first.'
I would do my part if she texted me and I replied with a photo of my bare chest.
