whenever you are wearing underwear and you get an erection so big that it pulls it tight and sucks your underwear into your ass crack causing a wedgie of mass proportions that can only be pulled out by reaching in deep.
i had to stop wearing underwear to the strip club's because everyday i went i got a boner wedgie and i soon developed some form of anal rash.

When your boner is so hardcore that it stretches your underwear taut, delving right into your crack.
My Boner Wedgie has been hounding me for hours.
