Secondhand Boner

When you feel sexually attracted to someone on behalf of their chemistry with someone else

Jack had a secondhand boner for Olga and kept on telling me to hit on her

Beer Surfing

When one drinks beer in spaced out intervals through out a long period of time in order to stay constantly tipsy without crossing over into full-blown drunkedness.

"We beer surfed throughout the weekend."

"Hah. Beer surfing's just expensive. Why not just get loaded? "

"Because we had a good time and absolutely no hangovers to speak of."
