To initiate positive change in a new romantic relationship. This could take the form of telling someone you like them, asking someone on a first date, or kissing them. Pulling the trigger can also be shortened to p.t.t.
"How'd it go with her last night? Did you pull the trigger"
"Oh, you know... a gentlemen never tells."
"You're the man!"
A practical joke in which a hotdog is gently leaned against the face of a sleeping friend, creating a tiny ladder between a pillow and the friend's face. A successful hotdog ladder is achieved when one's fingers can be walked from the base of the ladder to the top without waking the friend. It should be noted that the wiener is not intended to be phallic.
Joanna fell asleep early last night and we gave her a hotdog ladder. She was pretty pissed when she woke up.
