An erection in the morning that makes your covers look like a tent

"Yeah I slept really well last night, woke up with a bed tent"

Fortress Bed Tent 

A normal tent used for camping with the bottom cut out fitted around a mattress. Not to be confused with a normal bed tent, which will usually not be completely enclosed

"Yo, check out this bed tent I got to feel cozy"

"That's not a bed tent, that's a Fortress Bed Tent"
