Flexative

Birthed from the word 'flexable' this verb is commonly used amongst morons that believe adding 'ative' to the end of something makes them appear more intelligent.

This word is also used by those who go on camping trips and have too much time on their hands.
Ouch! My legs sure do hurt from this hike, I wish my muscles were as flexative as your mom's vagina.

Flex tape

A tape type of product from flex seal™, mostly known from the two videos of jontron; "waterproofing my life with FLEX TAPE - Jontron" and "FLEX TAPE II: the flexening - Jontron". The company has made many commercials and Phil Swift is in most of them telling us the many used of flex tape. It can instantly bond in to almost anything and can stop any leak. Plus, some of them even work underwater!
Phil: Flex tape is super strong and when Its on, it holds on tight!
Jon: *shook* no Phil you're super strong.
